Automatic stalls in reverse.

Yes, the part number is ECH EC187 I think it was around $45, but I think you can get it cheaper if you shop around.
Ok cool thank you. Could a possible method of troubleshooting be to Hotwire the coil straight to 12 volts, then change gear and see if it stalls? If it does then the problem isn’t electrical. But if it fixed it, it is electrical?
