GPz 1100 A1 Unitrack won't start
Posted: Sun Apr 07, 2024 1:23 pm
Good afternoon.
I've not had the bike for long and all was good until yesterday when I managed to take it for it's first spin.
It started fine and ran well however after about 5 miles the DFi warning signal flashed at me and so I headed home.
When I got home I switched the engine off and it won't start, the engine won't even crank over.
I looked at the green light on the DFi box and the DFi trouble code was number 23, which is... perform "engine speed signal test" (base manual p10-30), and inspect ignition system damage.
I did the Engine speed signal test first thing and it was 0v when ignition was off and 12.78v with ignition on. I decided to do it again later and it was 0v with the ignition off however it was only 0.9v with the ignition on.
Any clues what this means and what to do next to try to rectify it?
When I try to start it the petrol pump sounds and the starter relay clicks once on each attempt to start, I've also completed the Starter relay test. This was as per the manual so I reckon that's ok, also if I unplug the kill switch there is no click on the starter relay so I think this is ok.
I've had a good chat with the previous owner Simon (Simonic = great chap) who mentioned that the starter motor was a bit lazy.
The fuses are all ok.
The wires/connectors to the coils look fine as well.
The battery is a Banner 20 Etx and was new the end of Jan 2024, is on a Oxford optimiser thingy.
Cheers
Stu
