voltage at battery

[MikeWa]

So at 5000 rpm with all lights on (high beam also) I should be getting 14 volts at the battery if amps are at or below 30 amp. right?

 

Yes.... If your electrical connections are good and the regulator/rectifier are good.

 

Remember a poor connection will reduce current flow, amps. So it can cause your readings not to reach optimum. A poor connection also creates heat at the connection. Over time this can discolor or burn wires and connectors etc.

 

Poor connections are insidious phantoms because they tend to make current draw look low while preventing the charging system from reaching it's maximum output. That is why techs check both voltage and current. A short on the other hand is generally easier to find. They cause to much current flow. So shorts will blow fuses, send up smoke signals and in general create havoc that is readily apparent. Also problems can be internal or external to the battery. So we try to isolate the problem to the battery, the charging system or the bikes electrical.

Remember, a battery can go bad internally at any time. If its 6 mo old or 4 years old.

 

Pull it out, and do a full charge on it, about 3 amps for about 6 to 8 hours, then let it sit for 24 hours and check the voltage, maby 48 hours.

 

If its bad internally the voltage will drop over two days.

 

If its bad, get a new AGM type battery !!! Talk to " Condor " !!

Ok what is a AGM type battery is that gel filled or acid

[heatonmt]

Condor do you hav the part number for the RSTD AMG battery and where to buy it?

[saddlebum]

it is acid filled but they use an Activated Glass Matt instead of the zinc and lead plates. It just uses much less acid and the battery can actually be mounted in any position, even upside down.

Will tok the bike in and dropped it off to start getting a paper trail on this.
