Hello All,
I got myself into a project with an MSU500 that I got after a dealership had done a teardown on part of the engine. The previous owner had been riding and it died. i was told the dealer said that whatever was wrong couldn't be fixed, parts not available. A bolt for the Starter Clutch had loosened and vibrated out destroying the Stator and shearing the Woodruff key. I have replaced all of that and put the motor back together. My problem now is I'm a Carb. guy never touched an EFI machine and I am getting no gas to the motor. I have confirmed that there is No gas getting to the cylinder, it fires with starting fluid. The fuel pump is working, i have pressure to the Injector and power to the Black and White lead on the Injector and the same on the Red and white lead to the ECM/ECU. I have been reading and trying to understand some of the troubleshooting steps that I've found. I also have done the test with the Injector pulled out and put in a container and tried, not even a drop of fuel comes out. I have also tried with a New Injector installed with the same results.
I know this is not a Simple system but any input, or suggestions would be greatly appreciated.
On a side note: This probably needs a new topic. but while i'm and this will sound foolish but.
Does anyone know where the Fuse Box is on a 2016 MSU500?? Believe me I've gone thru everything Under the hood. It is not in with or near the battery box as one manual says. Not one the firewall, inside out under the hood. I have spent hours working on both sides of the motor and Under it and I've not found it there. And after looking up a New Part for this I can't even find what are shown to be the correct Leads from the wiring harness to Plug into the unit.
I thank you All in advance for any suggestions or info that you might be able and willing to provide,
Robert

My 2014 Bobcat 3650 has started running rough. It starts fine. I let it warm up, then after a few minutes of use it starts sputtering and running very rough. Then stalls. It usually will start back up but continues running rough. If i let it cool off, it will run fine again for a few minutes, then repeat the process.

We see a lot of the UT400 with shift problems, not going into gear, popping out of gear, grinding etc. There is a bulletin Im sure everyone has saw about adjusting shift cable. That dont always fix it. I went round n round with coleman on couple units. We are a Coleman warranty repair center"AFS Small Engine Repair " I told them shift lever does not have enough travel . No amount of cable adjustment will increase travel . I extended lever with piece on flat iron by 3/4 of inch . This gave shifter enough travel to properly engage into gear completely . Last couple units to come in for this Coleman sent me a modified shift lever, with longer travel . Problem solved! Also , heads up if you get any new unit ,,,go over and check it out, grease all zerks, check air filter for being in backwards, check wiring harnesses for rubbing on rotating parts, brake hose routing , make sure not touching exhaust . These are just few of the more common failures I see .
