OK; here's the update. Finally got it up and apart. Found stator plug (I hope that's it-see pic), unplugged it; cleaned it and ran stator checks. Passed all tests; resistance was within specs and no continuity. Dielectriced it and plugged it back in. Replaced SCCR again (had a new spare lying around); also greased that plug. Pulled lowers; found other fuse box (!!!) and regulator. A bitch to get at behind and below radiator, but swapped it out (also greased plug). Changed oil (as long as I had it up); filter can wait till next change. Unplugged fuse for audio (everything goes to my helmet by Bluetooth) because handlebar unit was being wonky every once in a while. Reassembled trike; only 1 extra screw... (I know where that and from; left lower rear bushing wore out. I need to order a couple of new ones.) Current current (I couldn't resist...) reads 13.1 at idle and 14.4 while running at road speed. Oe wondering if that's too high? Doesn't get above 14.5; wonder if all the wobbly charging currents recently have weakened or fried the battery. I still have 12.3v when I turn the key... Thank you all for the help; further advice is always appreciated.

I thought of that first. Nothing has been added recently to increase load and it wouldn't happen right in the middle of a fuel stop. Increasing the idle a bit won't get back to a charging voltage; to get above 13 right now I'd have to add 1000 rpm. Before this happened upon starting I had 13.5 volts, any throttle brought it to 13.9-14.0 volts. Road lights dropped voltage to 13.5; high beam pulls .1 volt, as do dash lights. Voltage drops are the same now, but I no longer have the margin for the accessories. I don't use the electronics (radio, CB, tape) any more, but I have noticed that lately the system turns on randomly and pulls .2 volts when it's on. I think rain got into the control head; one of these days I'm going to strip that stuff and add a Bluetooth amp and Bluetooth CB that works straight to my helmet. I wish there was a separate fuse for that system because I would pull it; it has become a PITA to keep trying to turn it off when it's acting up. That issue has been going on much longer than the current voltage drop issue; I don't think they're related... Hmmmmmm....

I'll still have to check the plug but if it passes the checks at the regulator they will gonna long way... Thank you.

Thank you. I'll be careful. What I read was how to check for shorts and continuity; pretty sure I use ohmmeter settings for that. Do stator wires go direct from stator to regulator/rectifier? If so maybe I can check stator direct from regulator plug...

Last week during a long ride, voltage on my voltmeter dropped from steady 13.9 volts while running (13.4 at idle after starting) to 13.3 at speed and 12.5-12.7 at idle. I noticed change happened when I restarted after a fuel stop. Last fall I replaced ignition, fuses, SCCR, cleaned and dielectric greased all the connectors I could find, only to discover that the battery was bad (Auto Zone and Advance no longer load test batteries, or this you have been much easier). At present trike starts, runs and charges as long as I keep RPMs up. Doesn't seem like enough voltage drain to indicate a short anywhere; if something were grounded out there would be way bigger indications. At present trying to organize troubleshooting; things that come to mind are faulty connector somewhere, bad regulator/rectifier, or bad stator. Have article that tells me how to check stator; all I need to do is find the plug (or maybe last owner cut the plug out and soldered the wires??) but I don't know where to look for that. Ordered a new regulator/rectifier; I have been told that to replace it I need to remove radiator to get at it. I always thought that if the regulator goes bad, it overcharges the system and fries the battery... Last regulator/rectifier I changed came with wires and a plug; this one only came with a socket for one. Does it just unplug, or do I have to get creative? I could really use some advice and maybe a couple of pictures, so I can trace this down before it becomes more serious. TIA...

In our move south and some PC issues I had lost this site. Thank you so much for your email; now I have found you again!!! And just in the nick of time; I'm gonna need help troubleshooting an electrical problem. This site is worth a lot more to me than the paltry $12.00; as long as it still goes to you it's not worth the time I would spend to stop it. A workman is worth his wage; I read that somewhere authoritative... And thank you again for all you do; these great machines are getting scarcer (also their replacement parts) and as my mileage rises I find I need more knowledge than I thought I had...

Quote: "I ended up bypassing the the safety system and the bike is working fine." How did you bypass the SCCR? Having starting issues on mine and I wonder if that relay might be part or all of the problem...

Update 11/18/25: Pulled and had battery tested; fully charged and tested fine. Cleaned all connections I could find, Dielectric greased them. Tested starter relay; no continuity with power applied. Changed relay. Still the same issue. Pulled and checked SCCR; tested ok. Can't reach starter terminal to apply power directly. Pulled ignition switch; ordered new one as I'm pretty sure contacts are toast. Also ordered new SCCR just in case. djh3_88 has built an ignition bypass relay for me; waiting for shipment. Pulling bar switch housing today to check and clean contacts. Only other thing I can think of would be a worn and partially broken wire somewhere; I think if a wire were chafed and grounded I would be blowing a fuse somewhere; fuses are all good. Haven't heard of any self-resetting circuit breakers on this bike... Maybe intermittent ground issue? Other than battery ground terminal I have no idea where any other ground wires/straps might be located. Very frustrated at this point; hoping new parts wil help.

2011 Hannigan Venture, ridden every day since purchase 9/2024. On vacation for 3 weeks; trike was parked and covered. On return, trickle charged battery to 12.5 volts, turned key; everything looked normal. Neutral light, clicking fuel pump, dash lights, 12.3 volts on voltmeter. Touched started switch; all power died. Thought I popped main fuse. Nope. All fuses checked good. Key goes to off; turns to start, power returns and 12.3v. Touch start button, power dies. Key to off, then on; power returns. Pulled and checked battery and cleaned terminals and connectors; all seems good. Trike started and ran well daily until I parked it; maybe it's mad at me for going on vacation without it? Wondering where to look first. Switch? Starter solenoid? Wires to starter? Starter short? Clymer is no real help at this point... Mostly it assumes that bike turns over. No clicking or anything; just completely loses all electrical until I recycle key. Weird. (Also posted in Delphi Yamaha forum.) Anyone have ideas?

Long trike day last week; drove to KY to visit Hannigan factory. Drove through storm front that should have been short; lasted through entire state of TN. 3\4 of the way through trike started misfiring, running porly, and lost acceleration. I am assuming that water got through either plug wires or ignition coils; as I pulled in to get fuel issue calmed down until I got back into rain. Next day things dried out and trike went back to running normally after awhile. Might should not have kept running but had nowhere to find wires and/or coils, or dry place to work. Thinking of replacing plugs, wires, and coils anyway (also changing oil on the off chance that unburned fuel managed to get by rings). Wondering if there is any way to increase waterproofing on these critical parts, as I seem to run in the rain quite a bit... On my 2005 RSTD I had a constant problem first year with rear coils and misfires; factory rep after months of troubleshooting scratched head and recommended aftermarket coils and wires, and coil relocation. Wondering if I should also do that here. Any advice? Thank you in advance, as always...

Bought a new helmet with Sena built in; added Sena to wife's helmet. Very happy but can not run wired setup on trike and Sena at the same time; no room for 2 speakers in each helmet. Planning to remove entire sound system on trike-tuner, amp, plugs, CB, wiring, etc. Adding Sena controller to coordinate extras I will use. Adding a Cobra AllRoad 75 CB with remote box, USB mike (if necessary) because it will plug into Sena controller, and also bluetooth to helmet out of the box. Sena comes with FM radio; phone wil cover everything else music, and CB will layer with all of that plus intercom. Leaving speakers on trike because I sometimes like to use them. Looking for an amp that I can plug phone and Sena controller into to pipe phone output through trike speakers if necessary. Needs to be roughly the size of the tuner I'm taking out, would prefer 4 channel output that won't blow stock speakers. Any ideas or advice? Thank you in advance...

Just checked coolant overflow on my 2011 Venture/Hannigan (90,000 miles, bought at 80,000 in 9/24); found huge oil in it. (See pic.) In forumsearches I found primary causes seem to be water pump shaft seals and Twinkie o-rings. Planning to repair both locations; parts for water pump seals and shaft are enroute. Can't find proper part name for Twinkie, or part numbers, or kits. Planning to r&r water pump shaft and seals and o-rings and gaskets in Twinkie, then flush well with Dawn and refill. I have noticed no trace of coolant in oil or sweet smell/white smoke in exhaust. Can anyone enlighten me with info on twinkie seals, gaskets, etc? Thank you in advance!!

Oil in my coolant also; discovered 2 days ago. A lot of sludge. Ordered pump rebuild kit and seals but can find no info on twinkie including proper part name. Need seals and o-rings for it; can anyone help with name, part numbers, etc? 2011 Venture, 91,000 miles.

Thank you. Is CB connection under trunk or near radio in fairing? (Thinking under the trunk.) Thinking this will be a pain either way. Will tuning work if I just hit transmit button without mic connected? (My boy hasn't sent me back the headsets yet...)
