Electrical & Chassis Tech / Starter Solenoid Failure Or Ignition Switch?
« Last post by weitrhino on 08:37:51 PM / 08-May-21  »
Over the last several months my car increasingly would fail to start. I always start it by turning the key to 'Run' and waiting for the fuel pump to finish priming, then advance etc key to the "Start" position. Let me say the engine fires right up. especially on a cold start. Turn the key and Boom! She's running. But lately I'd turn to 'Start' and nothing would happen. Usually I could bump the car in gear enough to jostle things and it would start right up with the key. Of course I could push start and pop the clutch on 2nd gear but sometimes I'd be in a crowded flat parking lot.

I was convinced the starter solenoid was failing.....again. My current starter was installed about 28 months ago judging by the purchase receipt, so I was a little unhappy to be 4 months past warranty. Last time I tried just a solenoid swap the new one was slightly different and would not fit the starter. Stupidly, a solenoid from RockAuto is $49 and  whole starter containing a solenoid was $73 with a $20 core rebate. So I ordered a starter from RockAuto yesterday and today I figured to pull the old one to make installation go quicker. After removal, I decided to jump it right from the battery and it fired like it should. So I started digging and found there was no 12V trigger voltage getting to the solenoid.

Eventually I tracked this lack of voltage all the way back to the ignition.



On the left side of the steering column is where voltage enters for starting, and exits to trigger the starter solenoid. 12V should enter the ignition switch on the Black/White wire and feed back out on Black/Yellow, and that wire runs directly to the spade lug on the solenoid. There are extra circuits involved if you have the ASCD system or if you have an 87 or later car with a clutch safety system.

My voltmeter showed no voltage on the Black/Yellow with the key turned to "Start" so I removed the switch which is only held by one small phillips screw.




Once removed, you can turn the switch internals with a small flathead and measure for continuity on the wired side. I had no continuity between B/W and B/Y with the switch advanced to "Start." The metal housing is only held in place by 3 small indentations on its perimeter. I grabbed my needliest-nosiest pliers and forced the indents outward.



Once inside, here's what you have.



As you can see, the inside is dirty and making poor contact to the copper plate. As you disassemble, pay attention to the orientation of the parts so you can reinstall them facing the right way. Lifting off the copper plate reveals a plastic disc with a small spring in the center which pushes the plate upward and toward the opposing contacts.



The plastic disc has two bearings inserted on opposite sides of the perimeter. Small springs are behind them. These bearings proved the 'clicks' when rotating the key from Off to On to Accessory to Run.



I wiped out all the old dielectric grease and dirt then brushed up the raised contact points on the copper plate taking care not to remove much of the surface. A kitchen scratch pad was used on the wired side contacts. Then I re-greased the housing inside and coated the bearings and plastic disc with fresh dielectric grease.




To finish the reassembly I used a punch to re-indent the perimeter of the housing. Now it provides continuity across poles and voltage as well.....and we're back in business.



RockAuto is getting their starter back.

Thanks Sideways...it’s pretty cool getting to work on her once again. Here is a clearance shot of everything back there..it’s crowded, but at least it’s weight in the back.

...I went to Harbor Freight and picked up a stepped drill bit set and some grommets..drilled a hole to accept a he 1.00” grommet for the pressure relief line back to the MAF.

...just remember to stop drilling early and test fit..very easy to overshoot the grommet size.

I lost my login info for my old account, and I don't even have my 87 SE any more. I just picked up an XE coupe that has sat for half of my life and is in kind of miserable shape. More active on the FB group but I'm glad to see familiar names still lurking the site.

What was your old login I may be able to retrieve it for you. pm me your old screen name and I'll see what I can do.
