Hello to everybody.

Before changing the OVP, I wondered if I could not make a test to know if my OVP is indeed deficient.

I thought to put the 12V directly to the exit of the relays (since in my OVP I have 2 relays).

With this installation, if it is the OVP that cuts the current, the 12V will always arrive to destination and I will be able to see if my engine stall or not.

But before making this test, I wanted to know if someone among you would have some recommendation to give me.

You need to search the database.
You'll find a massive amount of information regarding the OVP.

Simply put, the best way to test the OVP bearing in mind it's relatively low price, is to change it. The early ones are exhibiting faults now anyway.

If you have only 1 fuse on top of the OVP it's an old one, newer ones have two fuses.
If the fuse has blown, you will have other warning lights on the dash anyway. Do you have the SRS or ABS light on?

But the OVP also influences engine starting under certain conditions too.

My suggestion:

1. Search the database here.
2. Check to see if yoour OVP has 1 or two fuses.
3 If it has only 1, buy a new one.
Your car may thank you for it.

Good luck
