Hello folks, I have been given this HCT for restoration. (it will compliment my strobo spark and hand made tester using an oscilloscope to measure ramp fire time). I would like to know a little more about it such as manufacturer (Allen, Ford etc?) and pictures of original condition or restorations of this model. Thanks in advance . John
Trying once more time before I give up to post a photo ...
Sorry I'm having trouble seeing the big E at the top of the chart!
A few more pixels per photo would help.
Better! Nice unit!
I believe yours is made by Service Equipment Co. I may be wrong, but I think yours is the very first design. You need to fit a wooden box inside to test the coils. Beautiful looking unit. Contact Ron Patterson for further information. Ron has had more of them than anyone.
Should say Hand Crank Coil Tester! When I saw the title, I thought it was some equipment to test your hand crank on the front of the Model T!
I restored on of those that had 4 stand-off bolts for the spark coil ring. Finding a set of the insulators for those bolts was a real problem.
Finally I found a guy to make a set out of Delron.
Then another problem was getting the sparks to hop from the coil box terminal to the coil ring.
Everything was so close that the spark preferred to find other paths.
The unit performed properly, after a great deal of wasted time.
One more correction solved the problem.
The original spark ring was replaced with an Allen spark ring.
Here is the original spark ring photo.
If you contact me I can help out with a wiring diagram for a HCCT.
This type of HCCT is what I call a "Ford Clone" made by many manufacturers based on the original design introduced by Ford and sold via the Branch plant supply chain. Soon thereafter Ford turned the manufacture over to Fairbanks Morse in New York. Everyone started to make and sell then in a very similar manner with some minor non functional differences.
As a practical matter they are all functional equivalents.
Ron, you wouldn't know the Ford Factory numbers for the HCCT, would you? The special HCCT parts, not the standard magneto and flywheel.
The top level assembly drawing for the Ford HCCT is 18-Z-245. There is a suffix part # for all the main parts. I.E. frame, crank handle, spark ring and mainshaft/flang.
This thread from last year shows quite a few different models:
Your tester appears to be identical to the one that I keep on my desk in my office. It's a Service Station Electric, restored by Wally Szumowski. I bought it from him about ten years ago and gave it to my father. When my father died, I bought it from his estate. It's got more sentimental value than cash value to me now.
Thank you everyone for your input to this, all very useful indeed. Ron P, I would really welcome wiring diagram for the HCCT and I have sent you a PM with my email address, I am in the UK. I will trace the wiring out on this HCCT but its been messed with over the years and clearly wrong. Thanks John
Ron Patterson was a great help to me for every one of the 8 HCCTs that I restored and a good source of parts!
Thank you again Ron!!!
