Weird Weird HELP!!!!!!!!!!!!

OK

My 1990 lost power ...I have another thread on wiggle the starter solenoid and it would start but after a few times that didn't work

So I just got a new starter solenoid, hooked it up again no power


But if i run a jumper wire from the one red wire that plugs into the solenoid while its still plugged into the solenoid to the battery and turn key on i got power and it will start and run just fine and charge just fine


unhook jumper wire from battery and no power no start,


again i have no power and wont start unless this wire in pic is rum from solenoid to battery

WTF?

 

with this wire hooked up as shown in pic straight to battery...I have power lights will start run and charge as it should

unhook the wire.... NOTHING

 

Clever fix, but somethin's fucked in the wiring somewhere. No problem just using the jumper wire i believe, figure out the exact problem later.

 

with this wire hooked up as shown the 30 amp fuse is out...if the fuse is in and u touch wire to battery it sparks, with fuse out no spark and it will run great


with good fuse in and no wire hooked no power no start its dead

will someone that knows anything call me for a min?

 

with it hooked up like below two red wires unplugged from solenoid and hooked to battery i got power and runs as should (fuse out)



Plug red wires back into solenoid put fuse back in...no wire to battery...NOTHING NO POWER

 

Dumb question. But with wiggling wires and jumping and all......you did re-check ALL fuses to make sure not blown from loose connections or something didn't you?

 

no fuses are blown in front fuse block

 

why cant I just wire it this way for good? it runs and charge good this way

 

Because it's not right. Something is wrong. That something could lead to other issues. From a glance at the wiring picture you posted it looks like (black wire running to a much smaller red wire splice) someone has been mucking about with the electrics. If you screw around with it the whole thing could go up in very expensive smoke.

 

That is just a simple little small 2 wire computer fan installed over the R/R hooked up via a toggle switch straight to battery, no wiring on the bike was messed with

 

I would still run the problem down. It doesn't sound too complex. You have already isolated the circuit that is the problem. I have seen too many bikes ruined by faulty electrics.

 

How aboot the main fuse? Located on the relay itself........Looking at the wiring diagram I could help but think that and then I looked at your picture and there is no fuse in the pic.

 

With the main fuse in and two red wires plugged in I GET NOTHING NO POWER

with the fuse OUT and red wires streight to battery i have power and bike does as it should

 

MY money is your problem is right there at the fuse. All your doing is bypassing the fuse connection as stated.

 

Its a new starter relay and the fuse is not blown, and I have tried another fuse

the bike didn't do this for a month just did this all at once


I know im just bypassing the fuse, so why cant i just put and inline fuse in that wire and run it that way?

If it was somewhere else in the wiring it wouldnt do right by just bypassing the fuse

 

Do you have a meter?

 

Yes............

 

Remove the four blade connectors on the relay, one of them will have 12v when you install the fuse.

 

The gn yellow and two reds?

One of the prongs should have 12v? with fuse in

 

Forget the wires, just remove them. With only the cables hooked up install the fuse and one of the blades on the relay will have 12v. What brand and model meter do you have?
