Battery is good......Tried running a wire from the thick purple one ( starter wire ) to the positive battery cable...All I got was a spark....Tried cranking while someone held wire - no good....
Lifted coil packs and banged on starter just to see if it would crank- no good... Don't think it's VATS security light goes off when you turn key....Don't think its clutch switch either.... At this point I'm hoping its is the starter because everything is basically apart.. Are there any other tests I can run to see if it is def. the starter? |

Also use a bit of emery cloth on the two fixed contacts. ![]() ![]() Clean the Valley Drain at the bottom rear of the Valley if you remove the Starter. Also....if you disassemble the Starter, check by spinning the two bearings at each end of the Starter Armature for smoothness (those two bearings are very easy to replace with new bearings) and obviously check the Armature Brushes for wear. ![]()

Pull the end cap off the solenoid. Clean or replace the contacts and the brass washer. Worked twice for me.

However, Vette 73, for clarification when 12volts is applied (one way or another) to the purple (solenoid) wire and there is NO CLICK, then the solenoid armature is either stuck (not likely - but not impossible), OR there is an electrical fault associated with the internal solenoid circuit. Again, all this is spelled out in Marc's paper on "Diagnosing Starter Problems". But, just for clarification, that auxiliary relay that is often mentioned is a mod that applies specifically to the 90-92 cars. After '92 the start circuit was changed to accomplish the same thing, namely remove the clutch switch from the relatively high current (solenoid) duties with the help of a relay (which was incorporated in the 93-95 car's starter circuit).

Thanks everybody for your input on this .....Actually tried banging on the starter but still nothing, not even a click......I'm waiting for a friend today who has a test light investigate this further,I'm not good with electrical stuff......
I hear a lot of stories of starters getting wet but actually everything looks pretty clean on my car where the starter sits.....At this point in a way since I can get to everything,if it's the starter than I can just replace......While I'm down there I notice a decent amount of corrosion when I pull the boots from the cool packs.....I will get in there with some contact cleaner and freshen them up..... |
