Alternator

[winddancer]

I was checking my alternator this last weekend and at 3000 rpm it is reading 15.9v at the battery is this to much and do i need to to do the regulator upgrade? My worry is i have the new lithium battery and i don't want to fry it.

check all your grounds and connectors first . then do it.

if i had a bad ground it would read high at the battery?

[Mark Olson]

yeah , it don't know how many volts to kick out.

Here's something from Hippy Cain I copied - fairly recent post so you can probably search for the original thread.

"Another thing you can do to extend battery life is to check the voltage at the alternator. Over charging a battery will harn it quickly. The smaller red wire that goes to the alternator supplies the field voltage. If this voltage reads low (it will because it passes through the main switch, and several connections) you will need to clean the switch contacts and connectors. The other fix is to use a relay to supply full battery voltage to the alternator and use the original circut to activate the relay.  My 89 was overcharging it's battery all the time because the reg/rec was always seeing a false low voltage. I have installed a nice Bosh 30 amp relay, a 15 amp blade fuse and some 10 gauge wire and it now works fine."
