I have a 1988 R20 3/4 ton crew cab pick up. Used it for a few small trips a couple of weeks ago. After trying to start after the third stop it wouldn't start - just a repeated clicking noise from the starter. After a friend tapped the starter, it started. Got it parked, tried to start it. Started 4 times. Fifth start try, back to the clicks. The battery is 9 months old and had it checked. Result: good. Took the starter out (starter is 2 years+ old) had it checked. Result: good. Checked the positive battery cable. Result: good. Negative cable replaced 6 months ago. Bench tested the starter with a battery. Result: did everything it was supposed to. Bench tested with the connections from the truck. Result: did everything it was supposed to. Motor spun, tested the solenoid - moved in and out like it should. Tried a connection form the ignition switch wire to the starter (with the starter out of the truck) Did what it was supposed to. I'm thinking that perhaps the ground from the motor to the chassis is not making a good connection. When I tested it with the truck battery, I used jumper cables and ground right to the starter. I lost daylight so the next check will be to check the truck ground and to use a cable to ground the starter (while installed) to see if I can get more than clicks. Are there any other things I could try? Any information greatly appreciated. Thanks.
