tonk Posted May 1 Report Posted May 1 Can you guys recommend an auto electrician in the North Yorkshire area (or a mobile one)? Mate has just got an HP4, it has two block connectors in the back of the clocks, both 12 pins. Because of a missing clip, the whole dash has been bouncing around so much that every single wire has fatigued to the point where there's no insulation left. This means there is no neutral, fuel or indicator light (they are in a separate cluster). Everything else works fine. We've tried and failed to de-pin the multi-connector and there's hardly any play to pull much of the loom out to work on. It's also part of the main loom so we can't unplug just the front section. Add to that, BMW won't do anything apart from replace the whole loom which will cost stupid money in labour alone. Next step is to buy a probe tester but even then we can't repair anything. So the only thing I can think of is an auto electrician. BMW won't give us a wiring diagram because they want to plug in a diagnostic reader but Motorworks have confirmed that the loom is identical to the S1000RR, just different ECU programming. They can't seem to grasp that it appears to be an old fashioned broken wire problem. Sorry for the long post, but thank you. Quote

Damnthistinleg Posted May 2 Report Posted May 2 Is there enough visible harness to strip it back and do a solder and heatshrink job to replace the broken ends? Six inches* or so would be all you'd need if you can get your hands in. It's a fuck on but nowhere near the fuck on that stripping the bike right down for a full harness would be. Also, I'd have thought that used harnesses and bits would be easily available used, given how many of these are track/race bikes. Anything going cheap that you could pillage for bits? I'd be happy to have a look but I'm absolutely flat out with the cricket season starting at the moment. I've not even got the time to do my own harness. I'm in Kirkbymoorside if you're still stuck in a couple of months time when things have calmed down a bit. * - Stop sniggering at the back. Quote

There's no room to work at all, we'd have to take the front apart until there was enough room. I found one loom on ebay but it's only got one of the dash plugs, don't know why it doesn't have two. The main problem is that the wires have worn through so close to the plug. If it was cut off there isn't enough wire left to strip and heat shrink. But it definitely does need a graft, I've found a wiring diagram so I'll print that. I think he's happy to leave it for a while now, it's just the idiot lights and he's enjoying riding it too much to strip the front end at the moment! Everything else works as it should. Appreciate the advice, I'm not far from Kirbymoorside at all. If we're not fixed by the time things quieten down could he drop by? 1 Quote
Damnthistinleg Posted May 2 Report Posted May 2 Getting the front end apart is a given anyway. Probably the easiest fix on this is to graft on the ends of another harness, possibly adding a tad more length for convenience if that fits the routing. No problems with him popping down when I'm a bit quieter. I've always had what is basically a car and bike workshop that gets interrupted by working for a living, rather than the other way round. 4 Quote
