    Wiring in a new Regulator/Rectifier (need help)

    Ok well that's cool I will have to test that. Do you think that the bike not running well has to do with the charging system being bad? I have a voltage meter on the battery whille its running and its getting around 12.2v. Im thinking that since its not getting 14v its not giving the spark plugs...

    Wiring in a new Regulator/Rectifier (need help)

    Well after checking some wiring diagram i found this, it shows 4 wires coming out of the coil and only 3 heading into the wiring harness... witch means i haven't found the issue yet.

    Wiring in a new Regulator/Rectifier (need help)

    I also saw this just a moment ago, (cell pic so it might be hard to see) There are 2 sets of wires that are coming from the left side of the case, both have 4 wires coming from them. One set all the wires are white the other have more than one color. The set that has 4 white wires...

    Wiring in a new Regulator/Rectifier (need help)

    Yes I also pulled out the coil and the center part(witch im guessing id the stator?) looked for any bad wiring and it all looks grate. So I cleaned all the old oil out and got a new gasket and re-installed it all. Also i got it running well so i took it down the road, while wiring was all...

    Hey guys i have collected a few sets of carbs over time i have a set of carbs off a DOHC xs400 look to be in working shape and everything is there, I have cleaned them out but don't know if they work because i don't own a DOHC bike. The XS650 carbs came of a 80's model i believe. They look...

    Wiring in a new Regulator/Rectifier (need help)

    Hey guys sry for the late replay going through a move. Yes i have a magnetic pull from the coil, and a good one at that. I tried the radio shack rectifier from the 650 site and the same results only 12.3-12.4 going from the terminals on the bat. Don't know what to think of it. But im also having...

    Wiring in a new Regulator/Rectifier (need help)

    ok tried the bike with the stock rectifier and the new regulator and the voltage is only at 12.2 lower then it is when the bike is off... If the rectifier is bad will it keep the bike from starting? Im running out of ideas... the bike worked grate then all of the sudden started blowing fuses...

    Wiring in a new Regulator/Rectifier (need help)

    ok well the fuse was blowing because of some temporary wiring to the rectifier. So now im going to try the new regulator that they use on the XS650 site. Got one for $20 the other day and figured id give it a shot. Do you know if the rectifier needs to be grounded as a unit? i know the new...

    Wiring in a new Regulator/Rectifier (need help)

    well after some more work on the bike i think i have traced the wires for the fuse back to find the fuse its blowing in the main fuse. (some one took out the fuse box and replaced it with inline fuses) and after messing with it more i wound that with the key in the off poison I out a new 20A...

    Wiring in a new Regulator/Rectifier (need help)

    The regulator was a universal one that fit the stock specks, and i would have checked the field coil but i was blowing fuses to start with witch i would think that it would be more likely be the regulator that went bad then the coil. But I will check for pamcopete and see if I have missed...

    Wiring in a new Regulator/Rectifier (need help)

    Well i thought i had it figured out but after a test run there was only 12v on the battery when the bike was running. I believe im looking for 14v. I have look on the 650 site and on all the other sites but no one can tell me what the wires on the stock harness do.
