Alright this is going to be a long one. I am having issues with my MSD setup which consists of:
6530 box (I have two of them here)
8252 coil (two of these also)
85840 distributor (locked out)
Heavy wires direct to battery. Only two wires running to coil. Distributor wires are separate from any other wiring. Battery is grounded to frame, block, and then also a block to frame ground strap.
To start, I had a no spark condition with the first box and coil. Unit was for sure getting 12V from the heavy wires and from the trigger wire. Coil tested just outside of listed tolerance. Distributor tested ok. MSD tech told me the box or coil "had to" be bad.
So I overnight a second box and coil. It now starts every time and has spark. The issue it has is very strange. If you plug the laptop in and check the battery voltage, it will periodically read 15V with the engine off and 18V with the engine running. It will then act as though it has a "two step" set and will not rev over 2000 rpms and the timing goes crazy if you watch with a light. Tach goes crazy.
If I disconnect the battery a few times, the car might run fine until you shut it off again. I unhooked the alternator and had the same result. All retard settings are set to zero or disconnected.
I can literally turn the key on and see 12V. Cycle key and it will show 15V on the software. I have used two different volt gauges and confirmed the box is only seeing 12V. My Autometer volt gauge never changes from 12-12.5V while the software gauge bounces all over
Three different times MSD "techs" have put me on hold and then hang up. The advice they have given me:
-Download new software
-Make sure no wires are touching
-Send boxes in to be checked
-Ignore the voltage gauge in the software
Also another strange thing is that both boxes flash "code two" on the LED indicating low voltage. This is with them connected directly to multiple different batteries that have 12.4V.
The MSD box flashes "low voltage" but the MSD software shows that the box is seeing between 12-15V. This is on both boxes when they are new. I was told to ignore this
Any ideas before I order all Mallory or Crane parts? I'm beyond fed up with MSD and their service. I now have $1000+ in parts and overnight fees plus going on three weeks of headache
I've asked if it could be anything in the programming and they said no. I can post how I have it setup if need be. I typed this out on my phone so it is probably full of errors
Any ideas? Thanks
