Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.
Hey guys I'm new here. I have a 88 warrior that has intermittent spark. When I got the bike the guy said it needed a stator. So I tested the stator and the Source coil has .310, Trigger coil has .363 an .367, Alternator side has .05 to .06 on the three. Which all seem in range. I did find that the ignition coil was bad and replaced it. After I put the new coil on i got spark but only now and then. The bike won't spark while I'm holding the start button, but as soon as I let off it will spark sometimes. I ended up unplugging the voltage regulator and it will spark every time I let off the start button, but still will not spark while I'm holding it. What could this be?

I recently purchased a 2000 polaris xplorer 400 4x4. When I bought it the starter was bad, speedometer didn't work, and it had been sitting for 5 years. I replaced the battery, and starter. Changed all fluids, and got it running correctly. Then replaced the speedometer in an attempt to make sure the awd would be available when needed. And took it out for a couple hour ride with a buddy.
It ran great that ride with no serious problems just a little carb issues which I was able to take care of on the trails. Then a couple days later I decided to take it out for a ride by myself, again ran great no issues other than a couple times it seemed to cough and then take off again. That day when I was loading it I noticed coolant dripping onto the trailer and the overflow bottle was empty.
Got home and decided to drain the counter balancer, when I did that I got about 3 cups of coolant. Im guessing that it needs new seals and all for the water pump.
My question is how difficult is it to do the water pump and should I attempt it or should I send it down the road to the polaris dealership to get it done?
I have had this ATV since new, and no work done on the system before. It has an intermittent issue with starting for years but getting worse. Cranks but no start or have to cycle power. No Codes. There are times it starts right up and then times it will not start at all.
What I have done, new plug, new battery, new coil. Also, the manual I have has spec info for the H1 & H2, but when I check ohms & AC voltage & wire color, it is more in line with the H2 than H1.
Ok here is what I have done.
1. new plug then new battery.
2. checked and replaced the coil- primary was 5ohms and secondary was 20.4K ohms. Since my book said for the H1 the Primary should be less than 1ohm I replaced (new one had the same 5ohms, confused! H2 says 4.8ohms). Book says secondary should be 12k-20k ohms and it was 20K ohms. New coil did not correct the issue.
3. Stator, AC output while running was good, about 75 volts AC no load between the three yellow wires (but mine are gray wires like the H2). Ohms were also less than 1 ohm.
4. Crankshaft position Sensor. Again, H1 should have Blue & White but I have Blue & Green like the H2. I have 180 ohms across the Blue & Green wires, so this is good. But when cranking I have 2 volts AC. For the H1 book says 5 volts AC. But H2 says 2 volts AC.
So, is my position sensor putting out low voltage or do I have the stator assy for an H2 in my H1 ATV from new? Stator & position sensor are one assy. Has this ever been an issue that was noted? New Stator is $$$ so I don’t want to just shotgun a part.
Any help would be great!

Hey just picked up another scrambler 850 was told the tps was bad. This atv has been beet to hell. Wiring has been tinkered with the crankcase has been replaced recently and the motor rebuilt (can see horizontal scores thru spark plug hole where it’s just been honed out and rebuilt)
my guess is it was ragged out till the motor blew a rod and rebuilt but the clown that did it couldn’t get it to run again and sold it. When I bought it it would pulse and smoke black at idle and die with throttle.
New tps installed and it won’t run period. I went to celebrate it and I’m getting 5 volts on 2 of the 3 wires running to the tps. Is this normal and if so how should I celebrate it?
Hi, I just bought a used 1990 warrior and the rear is sagging low like it has a lowering kit but I’m not sure, does anyone know what it could be?

I have a 2000 Honda trx90 I got from a buddy for free he said it needed a carb so I put his old carb back on it to try to get something out of it and it does not have any Spark. I already replaced the ignition coil I don't know much about four wheelers but I am a technician so I do know my way around a motor any electrical help would be wonderful or specs I don't have the best digital multimeter either.
