So I kinda figured out the “short” issue in the kids truck. Turns out if there’s no bulb in the circuit (turn signals) it will immediately blow the fuse. Have you seen this? Is it normal? I can’t wrap my head around it.
That's fughed up.

No load in a circuit shouldn't cause a fuse to open. If there is no load in the circuit (bulb), there should then be no path to ground to allow the fuse to open.
Only thing I could possibly think of is there is some resistance/corrosion, something in the bulb socket that's shorting to ground when the bulb isn't in there.

Impressive Ed. One hour, same to put back in?

No. If I'm doing pistons and the timing chains I'm able to do those in 3.5-4 hours.
This one also bent the intake valves so it will take extra time to remove the high pressure pump (driven by the intake cam), the cam itself and get new valves in place and lapped in.

It’s methed up. Fuse blew with the socket completely gone and the wires separated. They’re working now so fug it…lol

Are the wires numbered? Case wants to go to all yellow wires.
They have a colored tracer line which you couldn't see in the pics. JCB German machines use all yellow wiring with silver stenciled numbers every 2-3 inches on wire runs.

Could be that socket got a bit squished and it's letting the 12 volt positive contact the ground when the bulb isn't in there to separate them.
In other words, whut u sed Ed...

I know this is the wrong place for this because all youse guys is skeered of big chainsaws that make noise n stuffs, but the boy is wanting to get rid of his MS661 "magnum".
It's gots the computater-ized carbutater n stuffs.
Comes with a Stihl 36" bar and a Stihl 25" ES light bar for the small stuffs.
VERY low hour saw, and nice plastics etc.
NOT cheap.
PM me if interested. Figured I'd throw it out here first.
