Just recently replaced the regulator on my 72T. I had bought one of those volt meters that plugs into the lighter. Was getting voltages as high as 16 V at freeway speeds and also noticed my batteries would tend to overflow fluid. Replaced with one bought on-line (black plastic). Went in easily and now voltage stays in the 12.0-13.5 range. Have noticed that on occasion just after starting, the voltage will be a bit low, 11.5, and I will have to rev it a couple of times to wake things up. This didn't happen with the original regulator.

clotz,
where did you get the meter and how much did you pay? is it an instantaneous digital readout?

I purchased the 'Road Pro 12 Volt LCD Voltmeter' for $12 from S. King company

Gives a continuous reading. Was the cheapest I could find and seems to work OK.

How can you identify if you have the alternator with and inbuilt VR. When I got my car it had no voltage regulator I have just assumed it has the VR integrated alternator, also one of the wires to the alternator has been cut I read somewhere that this is done when upgrading to a integrated alternator? The alternator is a Valo. What symptoms would running a car with no VR cause?

steve,
i don't think you could actually get away without having some sort of regulation. an alternator puts out wayyyy more than 14 volts without one and would quickly fry your entire electrical system. the regulator 'regulates' it's output down to 14 where the system voltage is designed to be.

So then this one from pelican should work on my car??

It should work. It just won't look original. If you're sure your stock one is the problem, are you willing to sell it to me? I'd like to play with one a bit... I'll give you $10, you pay 1st class postage...
