Deere CT332 Skid Steer Fuel Shutoff solenoid Issues

[Morspeed]

I have a ct332 that I juste replaced a fuel shutoff solenoid on. When the key is on you can push the solenoid in and it will hold and machine will start right up. It also releases fine whrn the key is off. It will not seem to pull in. If I jump the battery the solenoid will pull in just fine. Is this a battery issue? Not enough juice? It is holding steady at 12.4 volts today when I turned on the ignition to check the battery. I did notice yesterday when running with hydraulics on the batter was dipping into 9.8 volts. or so. Normally it will dip down to 12 volts or so and with the skid steer in park the battery would hold 14 volts. I tested the alternator and it is outputting 14 volts although the battery would not show over 12.5 volts while running. The only other thing I can think of is I added a power cutoff switch to the battery on the negative side because it seems something drains the battery when the machine sits. I had it on the positive side originally but battery still seemed to drain. So I switched it to negative the other day. Only thing I noticed it the battery cables I purchased to do this is a little smaller gauge than the original. Any thoughts or help would be great.

Check you Ground wire connections at the battery. I have the same problem with a Case Dozer after all the expense of replacement parts the problem was the Ground Cable.

It sounds like you're not getting full amperage to the pull coil, and with the other symptoms I would suspect you have a corrosion problem somewhere in the wiring. You should have the same voltage reading on the battery posts as you do the cables attached to them, that is, of course the first thing you test with a DMM. One would suspect a battery post was corroded, but you say it starts up ok; it wouldn't if that was the case.
Chances are that you have another heavy wire leading off of the positive battery cable that powers the panel and all that, that would be the place to start looking. Fuse panel, relays, exposed grounds, look at anything where corrosion could set in.
