Last week I had fitted a new overdrive gearlever wiring harness but the overdrive didn't work :-(
This week I patiently worked through the wiring with my digital analyser as most overdrive probelms are electrical.
First check - power to the switch - yes.
OK - now time to dismantle the gearlever gaiter so I could get to the top of the gearbox.
That allowed me to check if there was power from the switch. Yes.
OK good so far. I could see wiring to the inhibitor but that wouldn't be easy to get to and I didn't feel like pulling the connectors off to check if power was there as it wouldn't be easy to get them back on.
No matter - I could check if there was power reaching the solenoid with the the ignition on and the car in 3rd or 4th by jacking the car up and getting it on to axle stands.
This accomplished when I got under the car I saw the earth lead to the solenoid wasn't connected. Putting that back on and then checking the power said everything should be OK.
Whilst under the car I noticed the clutch slave cylinder connection was weeping as was the sump plug so I tightened them up a tad. Note this for later reference.
With the car back on the ground I carefully reassembled the gear lever gaiter and associated trim, even replacing a missing clip and screw.
So, the moment of truth - would the overdrive work?
Out on a test drive and I can report yes it does - hurragh!
Which is just as well because the clutch failed but I managed to jam it in third and switch between third and overdrive third to limp back home.
The 2000 is now back under the car port in shame until next weekend. I think I will take a long hard look at the whole clutch hydraulics again and see if I can sort that one out next.
I am absolutely convinced there's a great car lurking behind all this grief and I'll get to it eventually.
