RC Servo or PGM?

Thu Mar 05, 2009 5:45 am » Post: #1 » Download Post

Want to reset my power valves but when I switch the bike on the servo motor does not cycle. I have tried with the TPS plugged in and out. Also manually moved the servo from high to low and checked that the cables have some slack and that the PVs move freely.

How do I determine if it is the servo motor or PGM that has gone.

Yes it is set to run, but I must be honest, I must check that the kill switch has a solid connection. I did disconnect it while putting the harness/loom back on the bike(complete rebuild)

You can connect 12v directly to the servo, but I can't recall which connection. Try a search as it has been discussed before.

Checked the run switch, connection is fine.

I have searched and cannot seem to find it. If someone could be so kind as to mail me a wiring diagram for the MC28 I would be forever grateful.

Thanks Fontyyy, managed to check it out and the servo motor does work when I connect it directly to current.

What now? What do I check next. I planned to go the PGMII route but that was further down the line once I knew the bike was 100% mechanically sound.

i'd fault out the wires between the pgm and the servo motor, allthough it does sound like your pgm has prob had it, which is not unheard of

Turns out it was the steering lock which I had removed. Easy fix.

Some kind of safety device built into the steering lock.
Before I went through the effort of checking the harness I thought it best to put back all the road stuff and see if it sorted out the problem. Sure enough, when I plugged the steering lock in everything started to work again.
Bridged that connection and it is working.

Ah. So it wasn't just the RC valve not working then?

Yip, there was no spark either. Everything is fine now though.
