There is a more powerful starter available...someone will chime in... The relay will only mask the problem.. Rich

The relay doesn't mask the problem of a bad starter. If your starter is goin' bad, its goin' bad, the relay aint fixin that. The relay will cure the problem of resistance in the 30 year old, marginal at best wiring harness of a 914. The problem with the 914 starter circuit is this. By the time you run 12v from the battery up to the ignition switch in the cabin, all the way back to the rear of your car where the starter is, you've run that thin old wire about 10-12 feet. AND through a crappy switch. That creates resistance. Internal strands of 30 year old copper wiring corode. That creates resistance. Look at your old wiring, its not shiny copper its dull ugly corroded copper. By the time you add all of those factors, your starter doesn't get enough juice to close its own solenoid. All the relay does is shorten the path of voltage delivered to the starter. The crappy old wiring has enough balls to close the relay, but not engage the solenoid. Instead of running 12 feet of old thin corroded wire to your starter, you can run a few feet of fresh 12g wire from your battery to the starter via the relay. Also, its a good time to add a kill switch or remote start. To do remote start, you only have to jump the relay. So it cures a problem, but not the problem of a bad starter.

I had one of those and still had to jumper the wires off the realy to get my car to start on some days. A good relay, so I've heard and it was on my current car is the relay off of a Ford.
