My theory was correct with regard to my wiring dilemma and after altering it to the new configuration no more blown fuses. This is good as it was getting frustrating but it also means that I have a surplus supply of 7.5 amp mini fuses so if you are ever in need of one just get in touch as I have plenty to spare.
Getting that sorted was the start of a good (albeit bloody long) weekend on pROJECT mAYHEM - finished off the wiring on the Friday, ripped out the front passengers seat, ran the wires down the B pillar, found out the wires were not long enough, extended the wires and then put everything back together again. Having got that out of the way I then ran the wires for the split relay charger under the van, found out that the conduit was not big enough to accommodate the power cable for the amps and the cable for the split charger, tried to force it anyway before giving up in frustration and deciding to cloth wrap the lot instead. Connected everything up and decided to call it a day at sometime after 7PM.
Saturday I ripped the doors apart, fitted the motors for the electric windows, dynamatted round the speaker apertures, behind the speaker apertures and also on the backs of the door cards, tidied up the wiring and then put it all back together again. Cranked up the stereo and no more rattle from the doors - RESULT!! Following that I wired up the electric windows, tested them and was surprised to say that they worked apart from a minor cock up with connecting to a permanent +ve instead of an ignition +ve resulting in taking the glove box out (again) removing the radio (again) connecting to the right wire and then removing acres of skin off the back of my hands (again) putting the radio back in. It was only a minor cock up but bejeezus it was taxing on the patience to say the least. Finally finished at nearly 8PM and was very glad to leave the lock-up and adjourn to Tesco's for a much needed bottle of wine which disappeared somewhere far too quickly for my liking.
Compared to the previous two days Sunday was a breeze, ran through a cable that I had forgotten about the day before, got the battery fitted under the passenger seat, got the split charger and all the rest of the fuse boxes and the like installed and tidied the lot up. Again it all worked so my ability to wire auto electrics is either getting better or pROJECT mAYHEM has realised that resistance is futile. Finished off by getting the other roof panel installed, bypassing a dry soldered joint to one of the lights connections and then moving the switches to the correct places on the board. Moving the switches resulted in a couple more blown fuses (not those of the 7.5 Amp mini variety though) and that was that.
Will get some pics over the next couple of days of pROJECT mAYHEM illuminations in all its glory!
