A different kind of startus interruptus
Discussion in 'BNS12 Chat & Tech' started by pswiatki, Oct 10, 2019.
I am at my wits end trying to solve my startus interuptus issue. I'm having the EXACT same issues as pswiatki above. The starter gives a very strong "thunk" upon pressing the start button, then nothing happens. The fuel pump and dashboard cycle appropriately but no cranking occurs. I had installed MPH Cycles relay wiring kit some time ago and all was good for a year or more. I have moved the ground wires to the larger engine bolts under the throttle bodies, cleaned and checked the battery connections, disassembled and cleaned the starter button contacts, cleaned and replaced the fuses and contacts, replaced the starter and cleaned up all the relay plugs. If i connect my power probe to the battery it reads 13.2 v fully charged at the terminals and at the starter connection. If I use the probe to send battery voltage directly to the starter solenoid it cranks and starts EVERY time. I have load tested my Anti Gravity Li ion battery (480 CCA) and my tester says it's good. When this all started it would take between 5 and 20 times hitting the starter button to engage the starter then eventually that went to "never". I love this bike when it starts but I can't ride it if it won't start reliably and I'm now so frustrated I'm actually considering the unthinkable... Help!
