Hello all! I promise to make a proper intro post once everything is in order, but really need help on this one.
After becoming a new owner of a 2007 Speed Triple, I noted the typical slow cranking. To remedy, I performed DEcosse's famous Power Starter Mod-
4GA Battery Positive to Solenoid In(supplemental)
4GA Solenoid Out to Starter(replace)
4GA Battery Neg to Engine Ground(Supplemental)
After triple checking everything, I reattached the battery Neg and attempted to start the bike, but got absolutely nothing. No clicks, nothing. I then attempted to remove the solenoid from its mounting point to inspect, and was welcomed with a rapid electrical clicking followed by white smoke and electrical burning smell from the solenoid area. I disconnected the battery and closely inspected the solenoid connectors and cable harness. The solenoid is obviously cashed, as but luckily after pealing back the cable harness insulation, the main harness looks unharmed except some sort of ground wire coming off one of the little black connectors on the solenoid.
looking closer at my 4GA lugs I attached to the solenoid, I believe I know where I went wrong, but wanted to confirm-
1/4" lugs were unavailable, so I opted for 3/8 when I made my cables and neglected to file them down. This caused the lugs to rest on the connection pads of the 2 black connectors coming off the solenoid-
Looking at the attached pics, does my assumed cause of failure sound plausible? Looking at an electrical diagram, one of those little black connectors goes to Ground, the other goes to a leg on the Relay. I'm very curious what their purpose is, but more importantly, could I have damaged anything else further up the harness? My guess(hope) is that it stopped at the solenoid.
Bonus question, am I correct to assume that this is Engine Ground?
All insight is much appreciated!
