Hopefully someone out there is a T-Boss 410 electrics expert or a Massimo mechanic is viewing this. I parked my 410 and it was working great. I came back a week later and attempted to crank it and nothing. Turned the key and no power. Figured it was a bad/low battery so I charged it. Still nothing. Attempted to jump start it and still nothing. Usually when I put the key in and turn it to the first position, the display comes on and I hear the ECU and other items boot. Now it is doing nothing.
I slowly went through the electrical system and found the main fuse attached to the starter relay, part 71602 (pic 1) blown. I figured replacing this fuse would fix my problem. It didn't. I then ordered a new starter relay thinking maybe that part had gone bad and caused the fuse to blow, but a new relay did not fix the problem.
I have found a work around for starting the machine. If I take one of the purple/black leads (pic 2) and insert one of them in the bottom right of the starter relay (pic 1 and 3) then the machine will get power even with the key in the off position. I'm bypassing something but don't know what. I can use my right hand to hold the wire against the lower right of the starter relay, reach over and hold the brake with my foot, then take my left hand and turn the key and it will crank. As soon as I remove the wire from the relay the machine shuts down. I have even removed the power distributor box and it will still get power when I touch the wire to the relay. Of course this is not the way it should work but if I can't solve this problem somehow I may just have to rig a connector to the relay and bypass whatever is causing the electrical issue. Massimo has told me the purple/black wires on my model are not used.
Any help in figuring what my problem may be or other items I can try?
v/r,

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
