Normal volts
Hey all. I have a 2010 sg and the voltage gauge reads a little above 15. I was wondering if this was about normal? I recently added led signals and a load equalizer from custom dynamics. Could this have anything to do with it seeming high? Thanks for any help.

Never trust a Harley gauge especially if it is a voltage, fuel, oil pressure or temp gauge LOL.

suggest you put a digital voltmeter on the battery ( or trickle charger pigtail if you have)- and confirm voltage at the battery with motor running.
Regulator should keep below 14.8 VDC.
If your voltage is higher, you are looking at cooking your battery---maybe some very expensive engine management electronics.
If your voltage at battery is fine, then you know how much to subtract from the voltmeter reading to be accurate.
my current ( pun) ride is 100% accurate, as is my 88 FXRP. ---- the '95 FLHTC read 1.6 volts low, even after I wired the meter directly to the battery- previous with the stock wiring it read 2+ volts low. depending on the stock wiring and accessories used at the time, voltage drop in the stock wiring can give odd low readings.
