Loose Ground shorted Brake n turn lights

[JMont]

So i noticed on my 2003 Mastiff a clicking when i went to start my bike couple times b4 it would just turn over. So on a ride the other night i went to hit my turn signal and they both came on. I thought i smelt something burning so slammed the brakes pulled over n shut her down and lifted the seat to find a loose ground cable. I tightened it back up n she fired up but the turn indicators stuck on as well as the brake light. Now i have no turn signals or brake lights. So i pull off the gas tank cover today n unplug all the plugs one by one n connect them back. Cant find a burnt wire or bad place. Now the worst part is now the bike wont start at all. It just turns over n over. The thunder does not light up at all either. The module under the tank has 3 green lights that come on. Please help!!! I am wire stupid and do not understand the Thunderheart

May want to reset the fuse. May have tripped it.

On my pitbull there is a tiny box in the battery tray not sure where it is on the mastiff. It's tucked under the thunderheart. There is a tab that sticks out. You have to reset it like a breaker switch. I will see if I can find a photo and post a pic

look around in the battery box or it may be between the battery box and rear fender

So it looks like the wire plus lighting module is fried. So apparently i either need a new one or figure out how to bypass it. Still not sure about the not starting. I will fool with it more tomorrow n hopefully get it started again

Have to tried resetting the breaker? As mentioned previously.

The funny thing is after frying the module i still rode it for couple of days n then when i checked for problem on blinkers no more start. I had to have messed up something somewhere

found the problem. One of the push pins grounded out n melted in the plug

Can you identify the wire on each side of the plug and butt connect or splice it together? It can be permanent or temporary and if that's the only issue, should fire right up.

I found and fixed it. Had to snip the wire that burnt out form connector n run it straight. But problems solved besides a new module for turn lights which I can physically smell burnt. So order a new module for brake/turn lights n im BACK
