i have a 61 bug that i have had a alternator conversion fitted my question is, how many wires should be coming from it? i seem to remember that when i had my 72 converted it just had three, this one has three on the main power out, a earth and a second earth to the body. its only putting out 12.30volts at tickover and only goes upto around 12.45 at higher revs. shouldnt it be around the 13.5 to 14 mark? I know the chances are that the wires colours have been changed but if anyone knows what colour wire should be where that would be a massive help to.

Please help as its taken me over 2 years to get this car finished and this is the only thing thats stoping me from driving it everyday, i want to play!!!!!!

Alternators can be internal or external regulated.

Internal has a single post on the top and external has a 3 wire plus + some other wires

What is it??... internal or external regulator

Whatever..... it should be putting out more volts than that.

An alternator should step up to 14V-ish at lower vevs than a genny

this one has three on the main power out

You have the earlier Alternator that requires a external regulator which has 3 pins marked the same as on the alternator you need to mount the reg on the firewall and make a short loom between the 2 units

You havea earth screw towards the back on the top and theres a 4 or 5 mm screw thats the main output to the side of the 3 terminal post outlet

I read it on FACEBOOK so it must be true

ok all the wiring is as it should be but still low outputs and the feed to the red dash light has nothing. the wiring diagram i have says the dash light has to work or it will not charge. the wire to the dash light is fine i even ran a new one just to double check and the same but there is o.1 volts output from the alternator where it conects( behind the main d+ i think it was) anyone able to test theres and tell me what voltage it should put out as this is a brand new alternator and if its f**ked it can bloody go back!!... any help would be great...
