74 RD350 new wiring harness getting hot

[m in sc]

at a  stoplight. hit turn signal, bam. darkness. push of shame... been there.

Yup, first time bringing my RD to work, fired it up to show my buddies and bam lights out.  This followed by a number of kicks making me look ridiculous until I realized and checked the fuse.  This followed an hour long search of the office basement to find a fuse to get home.

At Deals Gap on the Dragon several years back. Faulty tail light\ brake light harness. After exhausting my supply of fuses out along the road. I figured out it was only blowing the fuse when the brake was applied. Tom Judkins (TJud) stopped and gave me a couple spares. I unplugged the tail light harness and made it back to the resort and found one of the tabs for the harness underneath the fender has punctured the brake light wire. Put on my spare harness and wrapped a bit of tape around the tab...

sorry off topic, but where are you guys getting your fuses? I went to home depot and got some but they are 1-1/4, just a little too big.

Ebay for me. Sometimes Amazon.

[paul1478]

thanks. I was hoping to just get some, Amazon it is!

I swapped out the fuse holder for one that uses mini fuses

[Dvsrd]

yup. only 1.

Makes sure that any short in any part of the harness stops you dead in your tracks, usually right in the middle of traffic..

Which is a great argument for getting a HPI or a VAPE

If you wire the vape into your stock kill switch, blowing the fuse kills power to the relay which will stop the motor. You will have to add in a bypass with a switch.

My poor neighbor had the single fuse blow on his Triumph at night, on a dark road, and off the road he went, and down.

Update: the wiring harness was fried. I put the old original harness back on and it's working fine, no heat no smoke! Now I have an issue with the Dyna S Vintage Smoke ignition. The rotor is not in line with the trigger at 2mm TDC. It's pointing up at 12 o'clock. So the spark happens on the down stroke. Any ideas?

Is the key in place that positions the generator rotor on the crankshaft?

thats what i was thinking.

ive never seen one clocked wrong.

I pulled the rotor off and then reinstalled it and that fixed the issue. The woodruff key looks fine, I don't know why the rotor was out of alignment. The notch in the ignition trigger is at 9 o'clock now, right where it needs to be to adjust the timing. Thanks for the ideas and the feedback!
