Ignition switch - wiring in a back up
I've been working on getting my father's 2001 750 to be a bit more reliable. So far I've sorted his overheating and charging issues, thanks to the members of this forum. On Sunday, he went out riding in a national park and had the bike shut off while riding. He was able to restart it and kept going. After stopping off to relax a bit, he wasn't able to turn it on again. Luckily he wasn't too far from home. I went out to meet him with some tools, and with the help of a very nice stranger and this forum, we traced the problem to the ignition switch. We took it apart and cleaned it out and the bike fired right up and got him home. I'm going to clean everything out more thoroughly with some contact cleaner later this week.
My dad asked me if I could come up with a back up to the ignition switch. We talked about just getting a new switch, but these seem prone to having the same problem. He wants to leave the bike as stock as possible. He's planning on taking some longer rides this Summer and doesn't want to get caught out like this again and have to have the bike towed.
I'm thinking of making a Y-harness so I could leave the stock wiring in place without splicing it, and have a simpler three pronged switch wired in parallel with the stock switch. I would put the new switch somewhere on the frame. It would be left in the off position, unless something went wrong with the stock switch again. In that case he would use the original switch to unlock the handlebars and leave it in the off position and use the new switch for ignition.
Is there an obvious reason why this wouldn't work? Thanks for any insight you could offer.
