The engine is killed via a NC relay, the engine starter is a NO relay wired in parallel to the ignition. Iirc both relays already have a diode. Are you suggesting that I should add a diode between the COM and +12V pins of the OBD socket? What kind of diode?
The older SG goes to sleep whenever the engine stops (as it should), and doesn't work when the engine starts (bumped or keyed on). Sometimes it will suddenly start working after a long while.
