Not sure if Neil will see this but I have a similar setup and can grab a pic. What do you want to see specifically? Coil? Dizzy?

For what it is worth, the following Mallory parts were installed on 1/07:

Distributor MAA-4768901
Coil MAA-29219
Ballast Resistor MAA-700

This setup runs like a champ with zero issues to date.

Sorry if it's too elementary in the explanation...

My current setup:mallory unilite distributor w/ e-spark module... with balast resistor.. with an accel coil....

So from the distributor, 8 of the connections go to the spark plugs. The 9th one in the center of the distributor goes to the accel coil.

The coil has a female connection, and so does the distributor.

Mallory coil 30451 is a male connection. How to you install this? Need to change my plug wire to something else? Or what am I not getting?

Looks like my coil is going bad when hot so I rather upgrade to the "correct" setup with the malory unilite then just buy another regular coil and have it break in 10K miles.

The only difference between this and mine is the accel coil 8140...

Maybe this accel crap is just that.. crap??

Here's another "hmmmmmmmmmmm'.. when I got this truck.. the coil was upside down... as in the connector is on top....

Are these coils only meant to be installed with the connections on the bottom???

Sounds like you need to source a wire with a female plug on one end and a male on the other. That, or go with the Mallory canister type coil MAA-29219. Here is a pic of the two versions, 29219 on the left and the 30451 on the right.

The orientation of the coil does not matter.

I'm looking for pics right now, but I didn't use an oil filled coil, I used the epoxy filled coil that dosen't need a ballast.

Look at my other thread, I have pics of the coil in there.

Neil,

Just want to see how you connected 30451 to the distributor and where you installed it... and if it is what Russel said.. that i just need to find/locate a spark plug cable that is male-female... and be done.

Thanks for looking for pics

I might be having the same issue as you Jeff.

The other day, backing out the driveway - truck just dies. Go to crank - and no start. Later in the day I start to diagnose --- hear the fuel pump, smell some fuel after cranking. Swapped ECU, checked ignition fuse.

Checked a plug for spark and nothing. So I start checking out the dizzy/coil.

1 - Searched the interweb and found how to test coil. I got 1.9 ohms which seems high as Neil said he got 1.4 and I tested another Bosch coil I had which read 1.2.

2 - Also found this video: First part of the test I got 10volts - covered the optics and there was no drop.

Sent Mallory tech support a ticket from their online form but figured I would cross reference with this thread as it came up in my google searching.

I am wondering if I am getting a voltage spike or there is something wrong with my system that I have blown coils, ballast resistors and maybe now a module. Or is the Mallory stuff just not that durable???

If anyone has any tips please let me know. This has been the most frustrating ongoing issue with this truck. Thanks

The coil install is very simple. It's just + and -, 2 wires to the -, one to the +. The same wires that go to your stock coil.

Hi all. So neither of these coils are available (from my searches) anymore. Anyone have an updated suggestion? Thanks in advance!

Regardless of this recommendation for the coil # 29216, a quick search through Google says this coil is not the best option. I'd call Mallory directly and ask for their recommendation.
Here some other areas to consider for the folks experiencing problems.
Josh, do you have a hulking sound system and CB in your D? I am not running the active power filter or curve change kit.

Mallory was bought by MSD, so most of the Mallory stuff is discontinued. FYI.

Yes of course - amp, 10" sub, etc. - doesn't everyone?!?! CB isn't hard wired though. I got the truck running earlier this week by literally advancing the timing a degree or two (no start) then retarding it a degree or two - started right up and ran for 5 minutes then died. Brought it back to where it was originally (i.e. where it hadn't been starting), and it started right up and has been fine since. Makes no sense. I've driven it 4 hours this week without issue though, so I'm baffled.

For what it is worth, my coil went out and I went to Pep Boys and got the Master Blaster 2 coil with ballast resistor. I am running the Mallory distributor. It has been in for a month and everything is fine.
