I have two 300ZX's ('85 & 87). One had an electrical issue, windshield wipers, internal fan blows sporadically (hot). It was suggested to jump the one Z with the other. Now the everything works on the car that was jumped. However, the electrical issues passed from one Z to the other. Mechanic said to jump the Z with a different make & model. I presume using an alternative electrical system might reengage the system. Is this just wrong or am I willing to try it? Suggestions?
You don't transfer problems from one vehicle to another with a jump start. Check the fuses and battery terminal conections. Something could be loose and the movement around it has caused the problems indicated.
