Desperate for help
 

My starter won't work and kicking that 300 is making the arthritis in my right knee flare up. Bike is a 2018 ec300 that I bought used and I suppose all the mods to the starter had been done by the previous owner because it always started great until recently when the started didn't disengage upon startup and that fried the starter relay. I have since replaced the relay and the starter motor. When I short across the two large terminals on the relay the bike fires right up but I don't even get a click when I use the button (it's new also). Even shorting across the black/white and yellow/red wires that go to the button does nothing. I'm stumped. Is my new relay bad? Could the diode module be bad? Thanks in advance for any help you can be. Ken

Look at the wiring schematic on page 68.
More than likely, the relay is bad.

Until you fix the magic button, can you use your left leg standing next to the bike to start it? Since they are both from Spain it will be kinda like kicking an old Bultaco. Umm, errr except backwards,,,,, twice.

I started my Bultaco that way back in the 60s. But the new bikes are pretty high up and it's hard to find a stump the correct height when you stall in an awkward location on the trail. A milk crate works fine in the parking lot.

I'm assuming you already have one, but for just in case ,if you have to kick a yz lever makes life easier .

Most of my rides are with other old people and they'll stop 10-20 times to talk during a 30 mile ride AND YES THAT GETS OLD.

I know it seems daunting but electrical is really pretty easy even though somewhat time consuming. All you need is a multi-meter. If you have the factory wiring diagram you just need to test continuity (ohms) of each wire on the starting circuit. The one that doesn't have continuity (no reading - OL) is where the problem is. If all wiring tests good then it is a component. You can test the switch and the relay using the same settings for testing the wires as you're only testing the in/out of the part. Remember, just because a part is new doesn't mean it's good!
