Enough voltage?

[LSCMike]

Alright might be buying a UDP soon and i took some readings with my voltmeter. 12.74v without car turned on (key might of been in the on position don't remember lol.) With car turned on it was reading 13.84v. Would it be safe to say I can run an udp, btw car does not have a/c. Will be getting electric fan in the near future, but I also have a gen3 alternator sitting in my garage. So what ya guys think.

Check the voltage with the lights on and radio going - see what it says then.

I had pullies on my car and the lights were very dim. That was with a new battery, new cables, etc. If you plan on going with an electric fan you are absolutely going to need that 3G alternator. No question.

I'm a fan of pullies. After doing the electric fan, AC relocation and pullies the car picked up 2 tenths and 3mph at the track.

Alright ill try that in the morning. BTW I am only putting on the Underdrive crank pulley. Did you put on the water pump and alternator one also?

I've got the crank and WP pulley on there now. With the 3G, there's no need for the alternator pulley. I get 14 volts at idle. Yours may be less in drive since mine is now a 5 speed.
