Ignition fuse keeps blowing

Postby 86GW1200 » Sun Aug 29, 2010 9:30 pm



Hi all, I'm the new owner of a one owner 1986 Aspencade. It has not run in 7 years. I did the things needed to start her for the first time in many years. I am having a fuel pump/relay problem and in the process of getting to the fuel pump relay I had to move the ignition box and coils. Now the bike blows the ignition fuse when I turn it over. Prior to that it turned over fine (just the fuel delivery problem kept it from starting). I was even able to give her a shot of starting fluid and it idles good - for several seconds. Anyway-any ideas on what I could have screwed up here? I think I re-installed everyr\thing. Help please. Thanks

I would be looking for a trapped wire, if you moved the ignition coils and ECU box, when you put it back you could have trapped a wire which is now shorted to earth and causing the fuse to blow. I would start by loosening the coils and ecu bolts that you tightened and see if the fuse still blows. If it does then you know you didn't create the problem, but if the fuse doesn't blow then I would be looking for a trapped wire in the area that you touched.

Thanks for the reply. I tried that very thing after work today and the fuse still blew. I read somewhere (I have tried ALL the sites to get this GW running) that the start button or and kill switch could be a problem so I took them apart after dinner. They looked ok, but the start button was a little corroded. I cleaned the contacts up and re-applied some di-electric grease. I lengthened the springs a wee bit and re-assembled. I don't know if it was pure coincidence or dumb luck, but the bike turns over again and will start with a bit of starting fluid...then dies. Now I'm back to the fuel pump/relay issue?

Thanks again.

I didn't know that.....I will revert to the "safer" method of pouring the gas in from a bucket :D

Not trying to be a smarta$$. Thanks for the heads up.

OK, I got a working relay and now have 12 volts going to the fuel pump. Of course, now the fuel pump does not run...and it is blowing the fuses again. I bypassed the relay and ran a line from the battery (through a 10amp fuse) to the fuel pump and used the battery gound. It blows that fuse also....now trying to find a pump.........

I would check the ground at the frame and clean the heck out of it...Sandpaper, dremel, clean it up, a lot of things happen when the bike isn't grounding well enough...

OK, thanks for the ideas..grounds look good. I got a good fuel pump and after giving it a rub down with wax--the chrome looks new. The fuel relay and fuel pump now "test" good. I am getting fuel and that little ticking sound people talk about. So, I started it (by putting fuel in the air box) several times. It starts and runs well----and no longer pops the fuse..wow that is cool. I just ordered a carb rebuil kit so once it arrives---I will be busy rebuilding the carbs..I took them off today to get ready....

Ok, another "newbie" question: I have seen reference to this on several posts,...What the heck is the "air box"??

Well, at the risk of not being PC, I call the air box the enclosed area where the air filter sits. I say PC because I only have 8 posts and am no expert...

I finished with all 4 carbs yesterday and replaced all of the vacuum lines (2 sizes) tonight. Soon I will slap the carbs back on and fire her up :?:

Update: I got the carbs back on and she runs like a top :D . I know it needs to be synced but wow does it have a smooth idle and no stumbles when I rev it up to 3k or so. I have some work to do to get it ride worthy but I think I'll put the false tank and seat on for a ride around the block soon. Thanks for the help guys/girls(?).

Well, I guess we can put this post to bed, kinda like that GA team today? Go GATORS!

Anyway, I took her for a few trips around the block today and it runs great. I have several other issues from the bike sitting seven years, but it runs great!!

Thanks again for this site and the help available. Great stuff.

Hey 86GW, come on up to "sunny" and "warm" Illinois and help me with my "86 1200 carb job. I've never done one before and everyone on this forum seems to think I can. I would sure love to be able to just dig in and get 'er done, especially since the shops around here charge $80.00 an hour !!! I'd love for my 1200 to sound that way. :oops:

Can't say I have ever been to IL. I do know that it ain't warm up that way this time of year :D I would be more than happy to rebuild yours if you supplied the kit and shipping. As far as payment, I could use a couple of boxes of .45 ammo. I replaced all of my vacuum lines also...there are 2 sizes. I am no expert, but have rebuilt many auto carbs before. I think you can do it. The hardest part is getting them off. You have to disconnect a lot of items...If I can do it, you can to. Take your time, go slow and when in doubt come on here and ask...
