No spark after wiring harness melting

Hey guys, brand new here. I had my wiring harness melt onto my exhaust cause my 99 grizzly 600 to cut off. Had no power or lights to dash and no electric start, nothing, just dead. Checked fuse by battery and it was blown. Replaced it and it blew again right away. Discovered wiring harness melted to the exhaust under the gas tank on right hand side. Wires were exposed and lots of melted plastic. Took me all day to separate and splice back together. Now I have power to everything and electric start works fine turning the starter but now I have no spark. Do you guys think I could have blown something else when the wires shorted out ? CDI or coil ? Not sure how to test or what readings a multi meter is supposed to read. Any help is greatly appreciated.

Welcome from Colorado.
I don't have a F.S.M. for the 600, but one can be had on tradebits for a few bucks.

You could have damaged the CDI with that shorting. Unfortunately there is no testing procedure for the CDI, except replacing it. CDI's are expensive, so you'll want to test everything else before assuming it's bad.

Ridgway is 100% correct above. Get the service manual. It has a troubleshooting section in it to test for no spark. Those manuals are dirt cheap for the information they contain and the money they can save you.

Your've probably checked, but what about the other fuses? Have you got 12 volts at the coil?

Welcome to GC and I don't know the resistance specs for the coil but it should have some. If you Ohm the coil and it is open you know it's bad.....good luck.

An "open" circuit means the electrical path is broken. Few simple examples are a cut wire, or a broken connecter or ground can cause an "open" circuit.

Which other fuses ? And how do I check to see if the coil is getting 12v. Sorry I don't know a whole lot about mechanical stuff...

You'll need a multimeter to verify voltage. You can buy one at any hardware store for 30$. You can also use a simple test light but they only indicat if you have power not nessassarly the required 12 volts.

You really need to download a manual so you can find stuff on the atv, it'll also have a wiring diagram to follow the colour coding of the wires so you know where they go, it's a possibility that you have joined a wrong wire & that is why there is no power to the coil, but you need the manual to be able to follow up & identify the components you need to check.
