I'm looking for a voltage regulator like the Jacobs Accuvolt to stablize the voltage. Right now, I'm getting a variation from 11.5 to 14v at idle. it's all over the place!

and when it varies like that I can't tune for ****. the FP fluctuates too much to get it idling smoothly. I'm using TEC II w/ a large aeromotive pump, powered by a red optima battery and 87 TII alternator..

Do you guys have this problem? I've seen these voltage stablizers on ebay for $35.. anyone use one of these? http://cgi.ebay.com/ebaymotors/ws/eB...category=33577

I'm not sure how well this would work by simply tieing into the battery..

any advice is appreciated!

Thanks!

 

fix the alternator and you won't have a voltage problem...

The parts you are asking about won't solve your problem.

The voltage should never ever drop under 12.6 volts, and with the engine running it should not be under 13.5 volts. It is is, then you have a bad alternator that needs to be fixed or replaced.
