Who's running Oem coils on total loss????

[Hirschfelt]

So, its known that the msd coils have an arc problem. I have heard that many racers are using them as paper weights and running oem kawi coils.

Does it matter which wire gets the white wire from the msd on the oem coils??

then the other 2 wires: the brown and yellow will go to the other wire on the coil by default.

I am using the ultra 150 coils. 1 wire = black, 1 wire = black w/ white stripe.

I ran MSD Coils for two years without a problem.
I have friends that have ran them for years without ever a problem.
Never heard of this arc problem.

EDIT: Talking about the newer single tower coils only.

That said, once I put my motor back together I will be using a stock Yamaha coil with Total Loss, but for other reasons.

The 3 systems I have to maintain, 2 of them are using oem Yamaha coils due to MSD dual tower coil failures.

I use ATP set up with OEM coils - no problems here

I had the problem on my hull, cf conducts pretty well, had to put them in an ip65 box.

Just got word from a few guys for the proper wirring. Its great now that my coils do not look like a christmass tree.

I am using an oem coil on my single channel digital total loss. Same spark, works the same.

I have ran both MSD & the Kawi coil. Love the Kawi coil set up, no more problems. MSD coils suck in salt water!

 

[Idok]

was that the problem with the 'hot throttle?'

 

[masterblaster]

so then you guys are running the oem yami single coil with the msd? can this work with the muti digital tl?

the oem coils work just fine with the old analog (sgl channel).you just use the oem elec. box incl solenoid and strap the control module to the outside of that box. it's been working for 15 years like that. the multichannel requires separate coils for each cylinder 'cause they fire at diff. times.

i thought that may be the case.so there is now way to do it with the stock ebox and oem coil with the dual dig msd?

 

[sflsurfrider]

has anyone tried an oem with a dual channel msd?

i wouldnt think think itd work. but just in case, how was it wired?

The dual channel fires each cylinder separately, which results in more energy per plug.
If you wire up an OEM coil, it will fire both cylinders at the same time, giving you a much weaker spark.
