MSD - 10 problems

I have been running a old version MSD-10 that uses the pro power coupler it has was worked great for the last 3 seasons but after a engine rebuild this year it wont even try to fire.I bypassed the coupler and it starts right up.
I sent my pro power coupler to MSD and it checked out good. I put it back on the car and same thing, It wont start. I bypassed the power coupler and it fires right up. Would anybody know if there should be continuity threw the coupler like you do threw a coil? Could it be my ignition box?
Any help would be great.

 

Hi there, it sounds like its your coupler but I am not familiar with them so cant comment on how to test them. It it couples 2 coils, you should be able to measure the resistance between each coil input and the output (ohms) and they should be the same.

I have just had my 2nd MSD-10+ go up in smoke, this unit had been tested by MSD last year so I am far from impressed with the reliability of these units. Its a pain in the arse as they only sell the 8 now which is no where near as grunty (probably more relaible though). Cheers, Graham

So it sounds like you agree, we should see some continuity threw the coupler?I wonder How did MSD not see that when they tested this thing? I will have to give them a call on Monday.
Thanks, B

 

please ask them if they have any used MSD-10+'s for sale when you talk to them !! Note there is a MSD-10 and coupler for sale on Ebay. Cheers Graham

 

MSD 10 has not been made or sold for over 3 years now...and there is not any replacement coil coupler available.. the newer model 10 boxes that use the single coil..p/n 8208 is still being produced...

 

I know that sucks. I had no issues with this ignition for a long time. I would really like to know what happen to it. I dont really have the money for a new one.

 

MSD 10 Plus

Been running and MSD 10 Plus for 5 years now and no problems.
just my 2 cents.

 

MSD have advised me that you need specialised test equipment to test the coil coupler for the 10, as I said there is a unit for sale on Ebay.

I had also ran my MSD-10+ for 5 years before failure and have now had 2 fail in under 12 months. Beware !! Cheers

 

i have a newer msd 10 with single coil i would sell for 650 plus the ride i had it in the trailer as spare fixing to sell out just let me no if you want it
