I picked up an old Sun Electric distributor machine. It was in great shape, and there is a date of July 7, 1965 on the inside of the cabinet. My problem is that the machine was made for points type distributors. It needs to be converted to work with electronic module and HEI units. My problem is I have no idea of what is needed to make it work with the newer distributors. What do I need to add?

Spent some time with them in the 60's but thats a tough one. Have you contacted Sun about it? They may even have an upgrade kit. :thumbup:

I have made initial contact with the parent company, and I am waiting to see if they can provide help. Sun Electric is now a subsidiary of Snap-On, and the main headquarters is in the Netherlands. Their website doesn't list much automotive testing equipment offered for sale, but I'm hopeful that they can still point me in the right direction. I figure that I might have a better chance of finding someone that has upgraded their machine, and can tell me what parts I need.

6567GTO thank you for the email address. I can use knowledgeable people if something goes wrong with the upgrade.

The customer service rep in the Netherlands was quite helpful. He gave me a toll free number here in the states. Well, it took three more toll free numbers, but I finally got the man in charge of parts for the old machines. Surprisingly, everything is still available for them - including manuals and upgrade kits. Only problem is nothing is cheap. I ended up ordering out an upgrade module that will allow the machine to work on electronic distributors. But should something go wrong, I'll be needing to get in touch with people that have worked on these machines. If anyone needs the phone number for Sun Distributor Machine parts, let me know.

Don't forget to contact Mark in the post above to see if he has the parts you need first.

I'm going to post the contact info here so I don't have to tear the house apart again looking for it. The toll free number for Sun Parts is 800-225-5786, but they only carry parts for their current items they have for sale - and they don't sell a distributor machine anymore.

The man you need to talk to for ordering parts is Roger Kunz, and his phone number is 815-344-6538. He can get absolutely any part for the machines, and is a pleasure to talk to on the phone. He can also point you to people that still service these machines. They are retired Sun techs, and the only problem is that they are located around Illinois (okay, only a problem for those of us on the west coast). You need to note whatever numbers you can find on the seperate pieces on the machine. I didn't know it, but the shell can contain any assortment of add on items. For example, there might be a dozen different dwell meters that would fit in the cabinet.

The amplifier module was a little lightweight box that is fully self contained and measures about 4x6x2 and has two brass terminals on top. You put your distributor lead on the + terminal and a ground lead to the - terminal. No batteries, no external power, but you fire up the distributor and everything works. Strange, but it does exactly what it is supposed to do.

I found out later that it is not needed for Unilite or the new Crane XRi modules, and all you need for these is an external power source.

Bummer, the guy had been retired for quite some time from Sun when I posted the information back 4-1/2 years ago. Hopefully he just gave up on the side business and is spending his time fishing -- but he might just not be around anymore. Try the 800 number and see if those guys might have another number that would work for you. There's a ton of the old Sun machines out there, and maybe there is still a source for parts.

Mark Saunders, who posted his email above, is a great help. I had several discussions with him before buying my machine. And, then . . . .I bought a pulse amplifier from him. He's very knowledgable and seems to have about everything. He could even have various panels on you machine repainted, and he has silk-screen masks to make all the lettering come out perfectly. I was not that particualr, and my machine is no great looker. But it works, so it's fun to play with. I promise you won't regret talking with Mark.

hei pulse amp

Can someone tell me how to hook up my sun pulse amp with my hei distributor and my sun 500 distributor tester?

If you have a complete HEI distributor, you don't even need a pulse amplifier.
All you need is a 12 volt power source. I use a cheap wall-wort, plugged into
the back of the machine. There are three wires coming out of the dizzy.
One hot, one ground and the third is the trigger for the machine. Don't look
for a proper plug to match the harness on the dizzy. The only one made is
on the Kent-Moore module tester and they don't make that themselves. I've
got one, but it was a long struggle.

What a coincidence! I posted yesterday in the electrical section about adding a sparkplug rack and coil to my 504 machine to add the ability to test msd type ignitions. I am concerned with isolating the plugrcak & coils from the machine. What do you guys think?
I added a couple pictures in the original thread as well, i am working on it now adding the switches and an amp meter to the 12v power supply for the CD boxes.

As far as the HEI connection i thought you needed another box, mine has a pigtail and what looks like a connector for a ford - can this be used?

I probed the connector and couldn't read any voltage. The pigtail has been added so I guess i need to go inside the machine to see where and what it is doing. I didn't see it when i redid the mechanicals and table etc, I didn't have that side of the machine apart.
It looks like a ford plug to me, anybody recognize it?

Ok, that's used for the trigger. To flash the light each time a cylinder would fire. It shows the spark pattern on the distributor machine. As in making sure each cylinder fires at the same time, by comparing the pattern.
Here's a diagram I found, and as you see, it is the pickup, pole piece, reluctor. (they have 3 different names), but mean the same thing.
You may still need a voltage supply

Is this it? I pulled the cover off one side of the machine to expose this add-on module, it looks like it is from a Ford.
The stud on the left is isolated and something clips to it - i think the alligator clip from the internal strobe light of the machine clips to it.
What hooks into the plug/connector - the box has no seperate power supply, one of those wires must be +12v supply for the box and the other 2?
Thanks, oj

That box IS the Ford ignition module. That plug in plugs into a Ford distributor for testing. Same as it would be on the vehicle itself.
The Red & Green wires went to the post on the side, they were joined; the stater (purple & orange) and ground (black) go to that plug extending on the pigtail. If i read the scematic right the Red is +12v and the green is trigger for the coil, thye should not be joined. It looks to me i should join the Red & White and give them +12v; the green would go to strobelight & ground side of the coil. The Purple & orange to the magnetic + & - pickup and the Black is ground @ the distr - is this right?
Can i both trigger on the Green the stobe light and fire the coil at the same time or will i get 12v thru the coil and damage the internal workings of the Sun, maybe do one or the other but not both?
The Red and Green wires joined and connected at the post is what is giving me pause.

LED upgrade

I have converted a model 504 with faulty flashtube to LED. If anyone is interested I can supply a kit to do this. It eliminates/replaces all the old high voltage electronics. Many different models use the same circuit as the 504. PM me if interested.

sun distributor machine

How about a little more info? What's involved in the changeover? Will it work on my 506? And, of course,
what kind of expense is involved?
