Thanks Danny, I’ll change it and see if it makes a difference.
I just started testing my leads and I found a boot on #6 that was melted right through so I may have found the cause of too much resistance, I’m changing it out and sleeping it with heat shield, fingers crossed! I always appreciate your quick replies and advice. One more question, if this doesn’t address the issue, can you tell me what tests on my ignition to make sure I’m getting correct voltage, resistance, etc.

Yes, read the link in post #2.Originally posted by smalliehunter View Post
I don't know, I've never heard of such an issue....do you think that will solve my ignition overheating issue?Leave a comment:

Should I change the setting to "Points Output Fixed Duty Cycle (MSD)", do you think that will solve my ignition overheating issue? I'm thinking it's related to resistance of some type, is there any specific tests I can do to make sure I don't have too much resistance?
What's really weird about this whole issue issue is that I thought I had the coil overheating resolved by installing the Dual Sync distributor, after I originally had all the overheating issues per my June 27-2017 original post. I drove the car for about 3000KM with no issues and just a couple weeks ago the car died just idling. I changed out the coil and got her back home and then it started running really rich for about 30 minutes and then died again, the coil was super hot.Leave a comment:

Yes, that's correct. Read this post #15 for more information: https://forums.holley.com/showthread...000#post244000 (New "Points Output Fixed Duty Cycle (MSD)" Output Setup)Originally posted by smalliehunter View Post
No, that's not for distributor/single coil type ignition systems.I just read an article on the web that says engines below 1.5HP per cubic inch, the Dwell Time should be set to 4.0 msec. My engine is 580 HP, should I try and change the Dwell Time to 4.0 msec?Leave a comment:

HP EFI Dwell Settings Possibly Overheating MSD SS Blaster Coils
I've previously posted on here before about my ongoing issue with overheating MSD SS Blaster coils and I'm still having issues with my coils and I just recently burned up the center coil carbon contact in my distributor cap on my Dual Sync. I've been doing a lot of reading and research on the internet and I'm wondering if my HP EFI Dwell Time Settings could Possibly be Overheating and burning out my Coils? My settings are "Points Output Adjustable Dwell" and Dwell Time is 2.0 msec. I just read an article on the web that says engines below 1.5HP per cubic inch, the Dwell Time should be set to 4.0 msec. My engine is 580 HP, should I try and change the Dwell Time to 4.0 msec?
This is my current configuration, all is wired as per MSD installation literature:
Dart 427 Stroker (580HP)
Holley HP EFI for my Hilborn ITB
MSD 6AL 6425.
MSD Blaster SS Coil 8207
MSD 2375MSD Pro-Billet Dual Sync EFI Distributor.
250 amp MechMan Alternator
Two Odyssey batteries installed in trunk wired in parallel.
My heads are grounded to each other and to the block, the block is grounded directly to the battery with 1 AWG arc welding cable. The block is grounded to the chassis as well and chassis is grounded to the battery. The grounds are solid on my car and not the cause of the overheating coils/cap.
I wired the car with the Infinity Box Intelligent Multiplex system, all wiring is done correctly.
I would really appreciate it if you could look into this for me and let me what could possibly be going on here. If there are any tests that I can do to check resistance in my ignition system or any other diagnostic procedures, please let me know. I’m tied of my car dying on the road and spending in excess of $1500.00 worth of MSD coils, as well as being stranded on the side of the road and really need and appreciate as much advice/suggestions/help that you can provide me. Thanks, Smalliehunter.
