Custom/Hybrid No spark on a new msd total loss pro digital ignition

[speedysprocket]

Have you disconnected power from it to let it reset, then tried it again? I had trouble with mine at first trying to get the right switch combination. The electric start and start retard switches were throwing me off.

Eric said he did a apart test and both were firing

Then call him back.

 

[sjetrider]

prolly not easy getting ahold of Sir Eric Malone guys, give the guy a break, he is trying to learn and fix his ski in a timely manner.

Check the coil grounds. The coils need to be grounded to the correct mounting grommet. I got lots of grounds on my coils and system.

 

[Pablo]

Which coil grommet gets grounded? I think it's the silver one, but not sure. I had this issue last year and I think I had the brass grommet grounded and was told that was wrong. My issue turned out to be a faulty channel from brain though.

ok so i just switched the lug wires around to the opposite coils and when i did that the back plug fired and not the front one like befor. bad coil, or bad coil ground??

 

[speedysprocket]

Lug or Plug?

 

[D-Roc]

I ground both grommets on both coils just because I can with my coil mount.

If you switched coil plugs and the other works than your coils are good. Check you pick ups

 

[lakeboy183]

Sorry I meant plugs. And what are the pick ups? I am new to these mad ignitions

i think he ment he switched the plug wires around meaning only the one coils is producing spark so the coil that was on the back plug is now on the front plug and now the front plug isnt firing meaning the one coil isnt getting power/spark ?

The pickups are located behind the flywheel . They act as the closing contacts, that tell the brain when to fire to the coils .

Correct. One of the coils isn't getting power

 

[speedysprocket]

Did you swap the wires going into the coils to see if it's a bad coil or if the MSD isn't sending power to one of the coils?

 

[D-Roc]

Or you can jump green pickup wires to see if you can fire the other coil. That would indicate a bad pickup signal.

 

[lakeboy183]

when i turned the s4 off one started sparking. is there another switch i need to turn off to make the other start?

 

[Matt_E]

No. short the pickup wires at the connector (a long staple works great) and see if you can get spark on each side.

 

[D-Roc]

The green pick up wires from the flywheel cover should connect to twin yellows as a cylinder and two more green wires connect to twin browns or orange. You need to jump the twin yellows together quickly for a second and then the twin browns or orange. The s4 needs to be set to run engine mode and not test.

I have the same issue right now, my msd is 3 weeks old. Lost spark on side of the brain while riding.

Hmm not being an expert here, but is it possible that a channel got fried?
Isnt it possible to try the 3. channel? I mean, if its setup up to fire at 1 and 2, couldnt it be setup to 2 and 3?
Sounds pretty ty, and i got a brand new system laying ready to be installed within 1 month :/
