1989 Isuzu Trooper 4 cyl Four Wheel Drive Automatic 162000 miles
A replacement neutral safety switch (NSS) for my '89 Isuzu Trooper with automatic transmission is over $230.00 for the part, plus labor to install. Not an option.
But the switch seems to be on its last legs. Twice now it has refused to recognize that it is in park or neutral, so the starter gets no power. I have to run the shift lever up and down through the shift channel a few times, then the NSS will complete the circuit and the starter gets power. (I think the circuit that gets completed is the starter relay ground circuit, but that could be wrong.)
Does anyone know where on this car, under the hood, I can find the two wires that come up from the NSS, and provide the ground for the starter relay?
I have the factory service manual for a 1990 Trooper, and found a connector on the right fender panel (toward the rear, a black connector) that is involved in the NSS, but I'm not clear which two wires in that connector are what I seek.
Looking at the connector from the top, the manual suggests it is the two black wires with the color stripe.
When the NSS quits for good, can I connect those two wires together to ground the starter relay and start the car?
Is there a better workaround when the NSS fails?
(Thank you. And I appreciate your forbearance in not pontificating a safety sermon regarding the NSS.)
have the same problem?
