John is right as for "testing" the starter; but not for other problems (as Dave mentioned)and also VOLTAGE DROP! As you all may know there ia NO direct wire to the starter [connection #50] to the ignition switch! There are a number of connections (and maybe a relay.. seat belt interlock.. see Tech. Bul. about by-pass mod.)! My cure (suggestion) for this is to: #1: replace the ignition switch
#2: Add the Bosch starter relay kit
The Bosch starter relay kit; I believe the part # is WR-1 and is about $10.00 retail and takes less than 1 hour to install!
This relay kit uses the ignition switch to activate the relay, then the relay uses BATTERY voltage to switch to the starter! There for the battery VOLTAGE goes directly to the starter and NOT through the entire car's wiring system to activate the starter! I use these on several of my other cars purely to "save" the ignition switches from having to endure higher amperage during starting!! Any one having a problem with "HOT Starts" will also fine this will fix that too! I have several of these kits available; if you can not find them. ED
