    Hello all,

    Im new here, first bike was a 550 maxim and 3rd and current is a 750 seca, both 83. My 750 is in great shape, but the signal fuses has blown on me 4 times in a row while just barely moving. The original fuse I had in there for 6 months no problem. I bought some fuses online, they are 10 Amp that I'm putting in. (6X30). Is this the correct amp? Are fuses bought online sometimes pure shit? Any thought? Thanks in advance,

    Joe

    Did the original fuse blow, or did you just change it for giggles?

    Then you have an electrical fault somewhere in the turn signal circuits or the fuse box. Do you own a multimeter?

    Yes, Should I test the wires going to each light?

    More specifics on this might help isolate to a specific circuit. Is it blowing when you apply the front or rear brake?

    Ok, more specifics. All lights work. I can turn the bike on, rev the engine, switch gears, and the fuse stays good. As soon as the bike moves, the fuse dies.

    Brakes can be pressed without the fuse going.

    6x30 so your still using glass fuses?

    open up the control and see if the wires have come lose from the little board could be the brown wire is shorting against the body of control

    if you remove the flasher and you are still blowing fuses problem would be in the main harness maybe a pinched wire.

    Well, I tinkered, toyed, unplugged some stuff and plugged it back in. Magically, it works again. Turns out its all made up and nothing matters.

    The failure will repeat itself. Next time be methodical.

    Jeputera,
    You did great trouble shooting just too fast ;) On our older bikes a lot of the connections have corrosion on them. It is normally a white power that forms on the connector ends. This powder needs to be cleaned off so you can see and feel the metal that is under it. If you have the time, remove the NEG lead from your battery and start to clean the connector ends. Do this one at a time, pull a connector apart, take a small flat screwdriver or something you think will work, clean the contacts. I think there is a spray out there now too that will remove the corrosion, add a little bit of diametric grease to help keep out the moister and move to the next connector.

    You can go through the whole bike staring from one end of the other, keep track of the connectors, only do one at a time and reconnect them. Once all done put the NEG lead back on the batter and you should be good to go. If you take the time to do this, look at the wires and see if there are any that have insulation that has worn off from being pinched or rubbed on the frame. If so electric tape or liquid tape that spot, let it dry and move on. Doing this just might save you from blowing another fuse. Good luck and keep up posted.
