ptt headache

[adaptolife]

The PTT on my '93 yamaha 130 has decided to raise and lower at random. Anyone have this happen?

[greasyshaft]

Probably a shagged switch or damaged wiring harness

Do a search... It does happen on different models and as I re-call, the switch (if equippped) on the engine sometimes corrodes up and has the issues you have.

The throttle T&T switch will sometime do the same.

You should be able to unplug the engine switch under the cowl. Try un-plugging it and see if it stops. If it does, that switch is your issue..

I unplugged and removed the motor ptt switch, and the problem is still there. Does the circuit activate a relay?

No relay

No relay on the PTT got to be a faulty switch on the console side or harness then
Try hooking the motor switch back up and unplug the square plug that leads to the front controls tilt switch should work motor side then.
Check you p.m. for a diagram

Yamaha motors have T&T relays so not sure what you are talking about

Throttle switch bad/wet if motor switch didn't fix

[adaptolife]

It was the trim/tilt switch on the throttle handle. The ignition panel has another trim/tilt switch, and the 2 plug together behind that panel. Unplugged the switch, and could not get the fault. Don't know if switch or wiring broke. Still got a trim/tilt switch on console and motor, so we're good to go tubing tomorrow!
