Bike won't start

boostedM · Mar 31, 2019

Bike has been sitting for a month or two on a charger while I removed the tank for some paint work. Put it all back together and when I go to start it, I just hear a "click....click....click" from the starter relay. Took it all down, made sure I had adequate power going where it needed to go. Jumped the leads on the relay and it starts fine. Ordered a new (used) relay, installed, same issue.

I suppose the second relay could also be bad, but before I go chasing ghosts, is there something I could be missing here? Never had a starting issue before I parked it and took the tank off. I'm sure that was coincidental, but I'm trying to cover my bases. Any suggestions are greatly appreciated

Most likely you battery that went bad. I had the same problem on my bike. It was the battery.

try priming the fuel pump by cycling the bike on/off with the key a few times before starting.

Wouldn't also have trouble starting when I jump the relay if it was the battery? It starts right up when I do that. I'll see if I can find another battery to test

First thing I did once the new tank was on. Been through probably 20 priming cycles as this point testing the new relay and such

What terminals did you jump? Did you actually pick the starter relay coil or did you jump between the positive battery lead at the starter relay and the lead leading to the starter? With the ignition "OFF," 12 volts should be measured across the positive battery lead at the starter relay and the lead leading to the starter. Disconnect the harness connector to the starter relay, measure between the two harness connector pins while depressing the start button and 12VDC should be present. Remove the positive battery lead and the lead leading to the starter from the starter relay. Turn the ignition "ON," push the start button and measure the resistance across the terminals from which the cables were removed. You should measure 0 Ohms if the starter relay is good. If the relay doesn't close the starter circuit, check the wiring between the starter relay and ECU pin 31 and the wiring between the starter relay and the starter button and fuse #3 (Key Sense) in fuse block #1.

is it possible you forgot to plug a connector in when putting the bike back together?

I jumped between the positive battery lead at the starter relay and the lead to the starter. I'll check these other items

I was pretty methodical when reassembling, but there's always a chance. I'm going to disassemble again today and triple check every connection

Update: lamuraz67 was correct. It was indeed the battery. When I first checked it, it was only slightly under 12v but I checked again today and it was down to 9. Got a new battery and everything works like new. Thanks for the input everyone
