Indy Electrical Question?

I had lights and tach before installing a kill switch and pipes and now I have no lights or tach. The only thing I did with wiring was disconnect the harness to the gauge pod to relocate the speedo cable and wiring harness under my engine brace. I hooked the kill switch up exactly the same as my 91' 650 is hooked up.

I swapped out the voltage regulator, unhooked the kill switch, tried switching the wires to the ignition and nothing. Made sure all the plugs were tightly connected and still nothing.

So my question is is there something simple that I am missing?

Thanks for any ideas.

the tach reads the pulse from the lighting coil. you have no lights or tach means you have no voltage on the lighting coil circuit. This means you have shorted the wires somewhere. You said the regulator was ruled out , I would check around the pipes and see if the harness is touching them somewhere and they have burned and are now shorting

Agreed, or you bumped a plug when installing the pipe and it just knocked it loose enough

I will go back and check all my connections including the main harness under the mag carb. These pipes are real nice because they don't sit anywhere on the belly pan except the mag side shock tower. Hoping something simple. Thanks guys.

I really don't understand this. I went back pulled carbs, checked tach wire, main harness and they were both still fully connected. The wire harness does not come anywhere near the pipes so no it is not melted any where. I tried a different headlight, tach cluster wire harness and no difference. Like I said before everything worked before I removed the stock pipe and installed the triples and the kill switch which is installed exactly the same as my 91' 650. So I am stumped again, jut like I am stumped about my 83' 600 issue. If anyone has any other ideas I am open to trying anything. Thanks

I think your harness is shorted to chassis somewhere. Try this..... get an old sealed beam headlight , disconnect the stator plug at the engine and disconnect the voltage regulator. connect one terminal of the headlight to the wire which goes to the regulator the other terminal of the headlight to the pos terminal of a 12 v battery. Connect the neg terminal of the battery to the chassis of the snowmobile, if a short is present the headlight will shine brightly. start wiggling the wiring harness and disconnecting connectors until the headlight goes dim. this should help you find the short.

What about testing the lighting coil on the stator? Stator's can go bad at any second. Wouldn't hurt to ohm the stator quick

mrholmquist, are you saying you think that a wire within my main harness is bared and making contact with the chassis causing a short. If so would this include the wires going to the rear brake housing from the caliper? I cant remember removing the seat and tank, so maybe one of those wires are bared and making contact with the chassis; otherwise the rest of the wires are inside a black plastic enclosure all the way to the headlight and are in good condition. I checked them when I had motor removed.

polaris650freak not sure how to check ohm's on the stator, please inform me how. Thanks

I looked my entire harness over while sled was running trying to find a short. I wiggled it all the way to the ignition. Nothing I moved or wiggled made a difference.

So my question is the lighting coil part of the stator. Will I have to replace the stator or can I just replace the lighting coil? Is this something I can easy enough do with engine in sled?

I will need a flywheel puller right?

Hey guys can I remove the stator and just replace the lighting coil? Looks like I can from pictures, but not sure. I have a stator from an Indy 600 I am going to swap the lighting coil, but would like to know for sure before I tear it apart. Thanks
