Hey so I have 93 rx7 that keeps popping voltage regulators. The battery is in stock location pulleys are stock. I replaced the charging harness bought a new battery and alternator, I went to the local auto parts store to get the battery and alternator tested and right off the bat I'm told my voltage regulator is bad... Wierd thing is I still drove the car for like 3-4 months no problem until the battery died. Any idea what might be going on?

 

what non-stock wiring has been done to the car?

 

As far as I know it's all stock, there was a sub, amp and turbo timer but I disconnected them...

 

elaborate audio installs and alarms are usually the source of electrical gremlins of that sort. Check over all the stuff again.

 

I'm starting to lean towards that I have a bad ground.

 

So I replaced the harness in the blue, but I'm thinking maybe one of the grounds near/ behind the front bumper might be bad.???

 

 

Danny,

The voltage regulator is an internal component in most modern alternators. The FD alternator has one included.

If you suspect the alternator is bad then remove it and have it load tested at your local auto parts store. Alternately, perform the alternator checks included in the FSM.

 

What is your voltage with the car running around the time the regulator goes?
