Ok now that the water pump is on my car I noticed that when I start her up the volts are below 12 and my lighter adaptors shows "LOW POWER" for my radar detector and CELL charger the volts will rise up to 13-14 if I reve it a couple of times above 4k rpms but I know that something is wrong. What could this be? How could I fix it?

loose belt?

 

well I now have the dual alt pully and both belts are new.
There is only like 1.2 inch of play in the belts right now. And the volts stay at normal levels after i rev it even when the RPMs drop to normal levels. would a loos belt do that too?

belt slipping until it gets warm enough was what I was leaning towards.

I suppose it could be a bad regulator in the alt as well. Mazda OEM or reman'd alt?

 

It came off my parts car so i am guessing it has a load of miles under its belt. It looks like the one i had with the Mitsubishi sign on the back. how would I distinguish the difference between the two types?

 

Anyone??

 

Sounds like your battery is going south.

Alot of electrical parts on the RX-7 and alot of other cars are made by mitsubishi electric's, which also makes electrical stuff like TV's to. Is that what you meant or was that way off, I didn't really understand what you were asking.

 

i need to know how to destinguish between a new alt and a reman one.

 

What's up, hey remember i had the same problem is the alternator regulator , remember that i had to install an external regulator just while i get a new alternator.
Hope is not that, cya.

 

anyone knwo how much a new regulator is and how you test your current regulator?

 

I beleive out volt regul. are internal and cannot be replaced but I could be wrong.

 

im sure its inside the alt.. just curious to know if anyone knows how to test it..

ill bet mines pooched or something.. after i had it rebuilt.. and got ripped off..

 

well this is one more good reason for me to go and buy an FD alt.

Why don't you just take it to an auto parts store, and have them test it? They will do it for free. And if it is bad, just buy a new one. They don't cost that much.

 

I'll say!
