Snap-on Distributor tester

Dave,
In your instructions above for using a GM control module (to test other than GM dist.), are you using an external 12-volt power source? If so, what are doing with the ground (negative) from it, to complete the circuit?
I recently picked up a Sun DT-504 Distributor machine and need to make (or buy) a pulse amplifier for testing electronic distributors.
Thanks.
Lee

 

I have a couple of Sun dist machines and the strobe works on neither one. I want to build a Pulse Amp but have to fix the strobes first. Any suggestions as to where to start on fixing the strobes would help.

 

I found some parts here, but they aren't cheap.

Anyone else try this and know how it all works?

 

I would be interested in this as well.

 

Bump for this old thread, and I have 2 questions:

1) my strobe quit [Sun 400], so could I somehow use a timing light as a workaround? if so, how would I hook it up?

2) wiring up a module to use with hei, msd, etc is outlined above, but could someone explain/outline the entire wiring instructions [for example, where to hook up the - side of the 12v supply]

Thanks!

 

454, the 12v supply hooks to the b+ terminal of the hei module..

 

Bert, the ground from the external 12v supply hooks to the body ( mounting screws ) of the hei module..
Sorry I did not see this sooner..

sweet, thanks dave! i bought this dizzy tester several years ago and it worked once before the strobe quit! i needed to tweak a couple more distributors so i drug the thing back out, and now am trying to remember how it all hooked up. i picked up a module, and have a 12v battery out of one of our quads so i thing i should have everything covered, hopefully. most of our stuff is msd any more, so if i can figure this out it would help a ton. thanks again!

 

Dave: I must still not be awake this morning, as I can't get it right in my head for some reason...but maybe my ignorance can help someone else down the road! So, care to fill in the blanks below?

GM hei module
W terminal [left side]:
G terminal [left side]:

B terminal [right side]:
C terminal [right side]:

MSD pickup
Violet wire:
Green wire:

Sun dizzy machine
Red lead:
Black lead:

12v source
+ lead:
- lead:

Oh, and while you're at it, could you figure in a work-around to use my timing light, as my strobe has quit?

 

Ok, I'm gonna guess at this, so everyone check my work:

GM hei module
W terminal [left side]: violet wire (+) of MSD trigger
G terminal [left side]: green wire (-) of MSD trigger

B terminal [right side]: 12v (+)
C terminal [right side]: black lead from Sun machine (-)

MSD pickup
Violet wire: W (+) terminal on module
Green wire: G (-) terminal on mudule

Sun dizzy machine
Red lead: 12v (+)
Black lead: C terminal (-)
Distributor lead: C terminal on module (????)
Ground lead: to distributor housing

12v source
+ lead: B terminal (+) on module
- lead: module body/screw (-)

Am I close?

 

Well, I got my Sun SDT working finally...I had to tear the thing open, and drip a little solder here and there, and clean some of it, but the strobe is working again! I need to throw on an MSD dizzy and see if I can get it to work via the module, but I haven't had a chance yet.

 

Chevy454 have you had a chance to try it yet?
