Misfire

[JJBRhino]

Any thoughts on weak battery or battery with dead cell causing misfire?

Voltage regulator will cause it

if battery is not hot it could not provide the coil voltage needed for the saturation cycle time. Battery is place to start. But also check your stator voltage production and your voltage regulator as James said. You not only need voltage but the total wattage to give you the electrical power required. You don't say how old battery is or voltage?????

Should have explained about battery. I just bought this Rhino 660 about a month ago knowing I was going to have to fix a few things but that was ok because of how little I paid for it. James has been awesome with advice on the primary clutch issue that was caused by previous owner letting someone service the belt and left off a $5.00 washer that destroyed the camplate and fixed sheave. Anyway back to battery it most likely has been sitting 6 months to year. Thought I had recharged it and it was fine for about a week or so and I was just confirming thoughts on it causing the misfire

If car is that old and sitting for a while......go through all the grounds...search the forum and do the ground mods and make sure the coil itself is well grounded and the connectors are good with grease.

Very definitely do this. Grounding is potentially a big issue with the Rhinos.

The grease mentioned is to prevent corrosion caused by the dissimilar metals being in contact with each other. Most any grease will do, but the specific grease used by mechanics is called "dielectric grease" at the auto parts store. The dissimilar metals with a bit of water between act as a "battery". The battery generates electricity which causes metal to leave one metal and flow into the other, hence the corrosion.

I have greased each and every electrical connection with a silicone grease and not had an electrical problem since.

I will do that actually have some of the grease I use on cords for my camper.

And what these old contributors really like, in addition to everybody else, is your follow-up to let all know what was fix.
Also please fill out your signature with some details as you will notice in others signatures it can give an immediate impression and direction to respond .

I have some more testing to do but looks like the voltage regulator is going to be the culprit. I unpluged from the voltage regulator, tested the three white wires with engine running
and got a reading of 23 or higher on the meter checking all three wires. Crazy or not but it seems the engine ran smoother with the regulator unplugged which to me is another indicator.

Click on the above link and you will be taken to the grandfather post that I mentioned.

Follow the thing to the letter and your problem will be gone, unless you also have secondary unrelated problems. This will get you going in the right direction no matter what.

Good luck, SteveS
