Discussion Starter #1
We replaced an existing mini starter with a new Hitachi mini starter using a remote solenoid. . .

PROBLEM: Starter would not disengage after starting engine for a few seconds?? We shimmed inside, outside, overall, filed edges on ring gear but nothing would work.
SOLUTION: Studied other posting, manufacturers instructions and came to conclusion that having jumper from " B" terminal on remote solenoid to " S" terminal on starter solenoid is INCORRECT. Wiring should be " S " terminal on remote solenoid to " S " terminal on starter solenoid... SOLVED PROBLEM..
REASON: Ignition switch shut off has enough delay working THROUGH solenoid rather than instantanous shut off from key ignition switch on " S " terminal. Might be reverse EMF magnetism from starter itself holding up solenoid disconnet or just mechanical time delay in remote solenoid spring pushing contacts open... Just changed wire location.. HORRAY .. THERESA

Why does my starter seem to “run on” after the switch is released?

This is a common complaint on Ford permanent magnet starters, although it can occur on any permanent magnet starter in the right conditions. This situation develops when the ignition terminal on the starter is “jumpered” to the battery terminal on the starter and a remote solenoid is used. Permanent magnet starters can actually produce power if they are driven from an outside source (i.e. the starter will act like an alternator once the engine fires and starts spinning). The current produced in the starter for this second or so will flow from the starter’s battery terminal to the starter’s ignition terminal and hold the solenoid in. This will cause the one to two second delay in the solenoid release and an irritating noise. The solution is to wire the starter per the instruction sheet, which will ensure that the ignition switch terminal goes dead the instance the key is released.
