tldr; Other than peace of mind, no. A '97 Blazer should have the 4L60e transmission in it. These transmissions have their known issues, the main one being the sun shell liking to separate near the hub. While the shift solenoids are not weak, these too can be a problem, but I'd suspect you would have seen issues with them well before now if you were going ...

What's making the clicking Although there might be other things going on, due to the symptoms, its probably the starter solenoid. When your key turns in the ignition, it completes a relatively light circuit between the battery and the solenoid. The solenoid in turn snaps two contacts together (click) completing a much larger circuit between the battery and ...

For me the first step would be to connect a booster cable between the engine and the battery earth terminal - to test if any of the grounding cables / straps have failed. You should then do the same for the supply cable to the starter... Only then could you consider the starter at fault.

I would suggest that you should make sure that the solenoid has a decent earth or ground - especially as you say there is no click. Given that you say you are re-building this car, have you just painted all the inner surfaces of the engine bay? If so, then the solenoid may not be contacting metal for an earth. You can test this by putting a cable between ...

The reason is that this is called “low power indexing” and is to reduce tooth to tooth abutment. How it is done is that there are 2 windings in the solenoid: the pull-in winding and the hold-in winding. The pull-in winding is earthed by going through the starter motor, the hold-in winding goes directly to earth. The 50A or so for the pull-in winding is ...

Thank you. I bought a brand new starter and it arrived with a test report. Report seems legit and all ok, except solenoid results. It indicates "Close Test (Pull in); FAIL" and "Open test: FAIL". Emailed manufacturer, awaiting a reply.

This is usually caused by the starter motor armature shaft bushings wearing out. Because of the worn out bushings the armature shaft gets skewed off its axis and binds in the bushing. Tapping the solenoid with a hammer (you could also tap the starter body and get the same result) frees the shaft and allows the motor to turn. If low quality bushings were ...

Could be the solenoid is going bad, but there is also a microswitch that closes in P, in series with the brake switch, to energize the solenoid. Might just be misalignment of that, or failure of the switch itself. If you want to tackle it yourself you'll need the WIS, which has all the descriptions and wiring diagrams (http://findingsaabparts.com/#wis, ...

As long as the one wire you have connected to 30 and 85 is sized to handle the load, and you have a switched ground, then there is no issue. As this diagram you linked to shows: The relay is designed so you can have a very small wire connected to 86 that only carries enough current to activate the coil in the relay and a thicker wire to handle the load ...
