What in the World would the dash have to with the alt?

[Guest Gp crazy]

Well i fixed the lights on the dash they were on all the time. now the alt is acting weird it charges the batt only with the headlights on with lights off and the dash connected the alt light is on & the needle is at 8 volts with the dash disconnected lights on or off it works fine what did i do wrong? :?:

it sounds like u have a short in the wire that feeds 12v to the alt, yes to the alt, im not sure what color the wire is but there will be a wire in the plugg that will have 12v with the key on, check that for a voltage dropp, (my alt only had one wire in the plugg, so it was easty to find the feed to the alt, I have a 3.4 dohc)

I hope this helps man

later
