Got the overdrive going eventually. It was really wierd, it would do nothing for perhaps 5km then suddenly start working perfectly. I took the cover off the adjustment and had a fiddle but made no difference. In the end i pulled out the solinoid and tested it on the bench, working fine. Put it back in and same problem, getting grumpy by now...
Went to pull it out again and when i was disconnecting the wire to the solinoid it just fell in half. On closer inspection it revealed the copper core of the feed wire to the solinoid was totally oxidised and no matter how much i cut it back it was still just crumbley oxide. No wonder it wouldnt work! Replaced the wire as far into the solinoid housing as possible and replaced it on the van. Works a treat now, anyway there is a point to this little tale of woe, Could this be the problem with Tiggers OD? Perhaps this is the cause of several unexplained solinoid failures? Its worth stripping back the insulation on the few inches of the wire nearest the solinoid for a look see. Even though the wire was rotten it looked perfect on the outside and also showed continuity on my meter.
Been using Iceman alot for trips to the beach and even just around town, its great and gets the looks! I plan to get another dollop of work done in a few weeks all going to plan. Next up is getting the interior sorted.
Well...alright then, maybe just a little...
