So you don't have one either.

I uses a testor, but what I am trying to do is clear a RED FAULT CODE Battery/Generator.

The reader shows Fault P00621 which referes to a Generator Light.

I can not locate what that fault actually is. Can someone help?

I can clear the fault, but It comes back almost immediately.

Thank you

Also I just replaced the battery, alternator, and belt - no avail.

No one has one.

Probably a voltage regulator fault, fairly common.

Thanks, so I replaced the Alternator the other day, isn't the requlator internal to that?

Or is this a code that only a Dealer can reset?

Thanks

The regulator I found on Pelican does indeed fit into the back of the Alternator. Since I replaced with a new Alternator from Bosch last week, I assume the regulator is ok. Also I have had no problems with Battery Run Down etc.

My problem is the Dash Error, which will clear then immediately come back.
I am stumped again!

As it turns out, it was the engine to chassis ground behind the passenger rear tire. Funny when I restored
356's and my 914, the bare copper transmission to chassis ground was the first thing I changed out when sorting out the electrics. The bare copper grounds built up resistance and then things went off.

The 997 gave me a battery generator warning light so I chased that first. When it would not clear I went after the grounds. Sure enough that fixed it. Even though they are sealed cables and connectors, the resistance build up was enough for the ecu to not be happy.

I need to stick to the cheap basics first. Lesson learned.
