A few days ago I went to move the 101 so I could get into my back yard and do a bit of a clean up. Jumped in, turned the key.... Click.... Not a solenoid on the starter click, just the crank relay click... Hmmm. Got my multi meter out, had 12 ish volts on the battery. Checked at the solenoid and had 12 volts there when the key was turned. Tried to bridge out the solenoid - zip. If I bridged out the main terminal, the starter would run, but without the solenoid operating, it doesn't engage...
So, next thought is 'how hard is it to hand crank start a 101'. Good thought, but I don't have a crank handle. A quick phone call to Mick, and an hour or so later and I'm back in my driveway with a crank handle. Well, what a waste of time that was. Young Army and RAF lads may have what it takes to crank a 3.5 V8, but as it turns out, I sure as **** don't...
So, last resort, pull the starter and see if I can fix it. As it turns out, a 101 start is about the easiest thing in the world to remove and 2 minutes later - I'm not kidding, 2 minutes - it was on the bench. Checked the solenoid with a meter, and it was open circuited - bugger. Got my soldering iron out and whipped the cap off the end anyway. Tested everything again - all good... Put it down to a dry joint on the cap. While I was at it I stripped everything, cleaned the main contacts up, pulled the motor apart - it is a reduction style starter - everything in good nick, just cleaned out the old hard grease and gave it some fresh stuff. Commutator was in very good nick. Put it all back together and bench tested it - bingo, all good. Bang it back in the 101 - it is dark by now, so it took 3 minutes to refit.... Turned the key.... and it cranked fast and started straight away. Yay...
Next day, go to move it again... Nothing... WTF? Checked for power at the solenoid while trying to crank - nothing.... Ok, got a different problem now....
So, I give the wiring a quick once over and found the issue - **** me I'm dumb sometimes.! When I rewired it, I found a break in the crank loom where someone had an immobiliser switch or something in the circuit, the wires were twisted together and had a connector on them. I removed the connector with the intention of soldering the joint up but guess who forgot to do that and has had a bare twisted crank wire hanging around the engine bay or 6 months...
Soldered that up and all is well with the world again.
Interesting how 2 different faults appeared at the same time though...
