I finally decided to do something about the starter problem on the rally FX. It’s a chronic problem with Corollas of this vintage. On the street FX I simply put a pushbutton in parallel with the ignition key. It works, most of the time, but occasionally even that does not, so there is something else in that circuit that is contributing to voltage drop. Instead of pushing the full starter solenoid current through the ignition switch, I decided to run it through a relay, the way I thought it should be.
I couldn’t find a spec on the current draw of the starter solenoid so I wasn’t sure if a typical automotive relay could handle it, so I went overboard and picked up this solenoid from POP. It could almost operate the starter motor directly itself, but it’s actuator coil only draws around .6 A. Here it is installed. Took the connector that goes to the starter and the side from the orignal ignition went to the actuator coil. Other side that goes to the starter went to one side of contact. The other contact went through a fuse to battery positive, should give direct juice!
So far so good. No problems throughout yesterday when I went to ESH and shopping.
