Today I installed new voltage regulator.
The car is now showing charging for 1st time
It pegged over to the right
After a bit it dropped down to about 3/4.
After driving 35 minutes it showed discharge when I turned off engine.
Also now the temp guage will not work
I checked the block temp with my heat gun it showed 185 degrees.
Does that seem acceptable?
This is actually the 1st timeII have driven the car and I am not sure what to expect.

I would really suggest you either write all the posts about your car in the same project blog with the year and model in the title or put your car in your signature. So when people read your posts they instantly know which car you are talking about.

On most cars, if you have a helper sit in the driver's seat you can ground the sensor wire to the engine block for perhaps one second and you will see the gauge needle. Jump up. If that does not happen then your gauge is bad. If it does happen then your sender is bad or you have a bad connection between the sender and the wire.
