I was trying to use your drawing and instructions in combination with the
drawing by MCathcart of the Hamman mod on this thread (post #316):
Hard to start when hot issue...
Unfortunately, besides your using a Bosch-style relay and MCathcart using a Radio Shack ice cube, the wiring also seems to be different - you run the resistor from Normally Open to Common, while MC runs it from Normally Open to Normally Closed.
These may be trivial differences, but since I have a pretty weak grasp of auto electrical systems and relay terminology, and I also wasn't sure about where the starter wire would be found, I had to abort my planned mod this past weekend.
I was wondering if you or another knowledgable member could provide some more specifics to help the more ignorant among us. Now that I have a Bosch instead of a RS, I'm ignoring the MCathcart diagram altogether. Having placed your 5-step instructions next to your diagram without confusion introduced from the other diagram, it makes much more sense. However, I need more detailed instructions on steps 3 & 4:A. How do find the starter solenoid wire? (Visual descriptions, references to Bentley, Haynes, or ETKA all acceptable)
B. Where would I find "a good ground"?
C. What is the preferred way to tap into the starter solenoid wire?
And one last question...does intermittent failure of my dash engine temp gauge have anything to do with this, or does it just mean that my blue coolant temp sensor is 3 years old and putting in for retirement?
