I'm still not quite ready to order an ECU. I have been doing a lot of resistance checks, etc.
The grounds on the ECU are supposed to read continuity ( 0 ohms) on pins 10, 20, 32 and 42 to the battery ground terminal with the key on or off. They are reading low ohms, 0.5 or so with the key off but all of them are reading about 82 ohms with the key on. That doesn't change with the booster on, but the bike starts.
I was reading the resistance at the orange ground joint connector, thinking about changing that out. With the key off, they are all under 1 ohm. Turning the key on the resistance jumps to about 200 as the pump cycles, then drops to 82.
I checked the resistance from the main ground wire from the frame to the battery, zero resistance.
All this said, adding the booster changes the resistance with the key off down to zero, but with the key on/booster on the numbers are higher and the bike starts. Then shutting off the booster, shutting off the bike with the kill switch and the resistance numbers are the same as before, the bike starts off the battery. Until the key is cycled off and on again.
I have a couple YouTube videos but I don't know if it's cool to post them here. Someone let me know and I will put up the links.
