Ground points on MR2's
Guys,
Just thought I would throw this out to the masses because two of the cars I have worked on in a row have had issues surrounding ground cables not being clean.
Issues that can arise, dash lights lighting up or flickering, improper idle (high or surging) moving all the way down to completely not starting, charging or even frying electronics or in these cars, the throttle cable turning bring red and melting.
Be sure to at some point clean your ground cables off with some emery cloth. It may look clean but under it, there could be corrosion.
Main ones to consider are:
One up front on the battery post to the chassis.
One under the intake manifold runners when you get under the car which then runs into the engine harness.
One on the transmission top to the motor mount.
Smaller one on the tranny to the chassis.
Some, like myself have gone so far as to run a 6 gauge wire or lower from a point on the block to the front battery post.
I'm not saying, go drop money on those grounding kits that were the rage in 1999. The stock points are good, just need to have a good connection. If one is not even connected, CONNECT IT. You need it there.
