[Tigers] Solenoid problem?

[Ron Fraser]

I just checked the wire diagram again

 

Check the WR, white/ red wire from switch to solenoid

 

Take the WR wire off the solenoid – attach voltmeter to it and turn ign switch several times while watching the volt meter

Thanks to all who have replied - struggling with the intermittent nature of the problem, nonetheless some updates below.

 

Checks in addition to those below:

- Solenoid mount has been checked & cleaned & tightened

- Voltage drop between battery post and S post when cranking is 0.45V; battery voltage otherwise

- Resistance between S post and solenoid ground is 3.7 ohms

- Jumper between battery and S posts cranks engine (but 90% of the time so does turning the key, so not sure how much that indicates)

- Cleaned all connections on ignition switch, barrel is a little sloppy in turning

- Resistance along brown wire is 0.3 ohms, no indication of flaky connection when flexing wire harness & connections

- Battery appears to be of a Nov 1994 vintage as best I can tell (which doesn't exactly much inspire confidence)

 

Time for a new battery at the very least methinks, then my suspicion is focusing on the ignition vs. the solenoid at this point.

I believe I have a solenoid problem but thought it worth checking with the collective wisdom here:

 

Symptoms:  Tiger turns over immediately most times, but regularly when turning to the start position *nothing* happens (no clicks, no noise, nothing).  This tends to persist for a few tries it then it will all start working again.  Happens occasionally on cold start, might happen more frequently when engine is hot but pattern not entirely clear.

 

What has been checked so far:

- Battery has 12.6V, clean terminal connections & ground, and battery volatage is making it to the solenoid

- Cleaned terminals & connections on starter

- Solenoid terminals & connections cleaned

- Solenoid voltage drop between battery & starter posts is in 0.12V-0.15V range (was north of 0.3V before cleaning terminals)

 

My conclusion is that the solenoid is flaky, but if I am missing anything please shout.

 

Cheers in advance
