  • Voltage drop somewhere

    My '89 LX sometimes will click a few times when I turn the key, then it will start. Also the windshield wipers run slow. Battery and terminals are new, starter is new. If I check the voltage on the starter solenoid when this is going on it is low- like 6 to 8 volts. I have cleaned the ignition switch, replaced it with a used one, and believe it or not, found a brand new one on ebay. I don't think it is the ignition switch. It affects the starter, the windshield wipers, and the radio loses it's settings when it happens. if I connect a wire to the positive on the battery and touch the starter solenoid it will start every time. I took out the fuse box and it looks fine. Fusible links are the cartridge fuse type. Seems like an intermittent connection somewhere. Any ideas would be appreciated as I am stumped!

    Have not had that problem but if starter is sometimes getting power and sometimes not then problem may be in connection between battery and starter. Haynes manual suggests checking terminals and wiggling wires. If the radio is invovled maybe it could br turned on while wiggling wires in engine compartment and listen for static. Could possibly double check by turning lights on and wiggling same supect wire.

        I did a search of the Internet on "starter clicks won't turn over" and got a lot of hits. This was at the top of the list

          This was a common problem on VWs,so common an aftermarket fix was brewed up by Bosch. The fix was add a starter relay between the battery and the solenoid. That was the Bosch way I think I can even remember the number I think it was WR1. The real fix was a new positive cable new negative cable and a ground strap from 1 end of the negative cable to the transmission body. You need to be sure the negative cable grounds the body and the transmission.

            The Starter Solenoid has a plunger inside with a copper contact that allows the voltage across. Sometime the contacts can get dirty or corroded and cause dead spots. Every time you click the key forwar the plunger rotates slightly and eventually it will find a clean enough spot to let the current across the contacts. You should be able to take them apart and clean them I believe.
