Hello there, ok just put the motor back in after a shifting problem and now it starts and go down the road get to 3rd gear and it died and would not start. look at it and find a blown 10 amp fuse then put a 15 amp in because it was all i had and started right up again, went down the street and got to 2nd gear it died again and blow that fuse and would not start.
also i put a used wiring harness for the reverse/neutral/temp lights from ebay could that be it or something else??

Welcome to the forum.

I would check for a bare wire somewhere that is grounding out and blowing the fuse.

Which fuse is blowing?

 

[newhope]

ok it is the 10amp IGN - ignition

Also check the ground cable connections on the motor and the frame. And verify that the harness you replaced is the same exact OEM part number as the original. Keep us updated if you can...

EDIT:
All the lights should work and be bright with the motor running. Are they? Does the same 10 amp IGN fuse blow when turning on the head/tail lights? Careful about putting 15 amp fuses in a 10 amp circuit... your Ignition switch is handling all of that current and can/will fry it.

ok will look, and i didn't turn on the lights when i took those 2 rides but i will make sure next time and check everything uses have said
will check back, thank you

ok lights ok and checked everything,
so i put new fuse in and it runs fine in 1st gear and 2nd gear i went up and down the street no problems but go to 3rd gear and it blows the fuse! Put a new fuse in runs fine only blows the fuse in 3rd gear!

Only blowing the fuse in 3rd gear is an oddball... Is there a gear indicator on the end of the shift drum in the 350 Rancher motor? I never had one of those motors apart yet... but sounds like something got put back together wrong? You can get the FSM for it HERE if you need one.

Hi: Unplug the connector to the ECU -- Check for corrosion on the connector and the pins of the ECU.

Will it blow the fuse with the motor not running ,key switch on and in third gear , if so what I might do is , pull the fuse that blows , put the two probes from a ohm meter into the two terminals where the fuse was , start disconnecting electrical plugs till you find the one that makes the continuity go away , then you will know where the problem is , even if it doesn't blow the fuse not running , you could start the engine , put it in third with the meter attached and do the same thing

Hi: This is a where to check the Main goes to the Ign. fuse and the Gears are right there also.

Hello, new to the forum. We're you able to figure out the problem or remedy it? I'm having the same issue. 2003 rancher 350 manual blowing ignition fuse when shifted into 3rd. Starts up and runs fine in 1st and 2nd.

I had the same problem with mine, turns out the carburetor heater had went short circuit, so that might be worth checking.
