Hello, I would like to make it easier to start my gas engines and I came across the CH Jump Start product on the C&H website.

I read a brief description of what the product does but I would like to learn more about it. For example:

How does it work?
How is it installed?
What part of the product is engine specific?
Can anyone provide a schematic?

My gas engines do not have an electronic ignition or a spring starter so I have had to lug around an electric starter. I realize that there are techniques to start gas engines but on those finicky days I think this product would prevent some frustration.

Any help would be appreciated.

Thanks

Norman

1. It works real good Hot spark at any RPM and retarded timing to reduce kick back.
2. It mounts on the mag coil with one screw. A battery jack and switch on the plane
3. Two models. One for Zenoah 45,62, 74t, 80t and one for Us Engines, some Quadras, and Ryobis.
4 NOPE its secret

Norman, here is the way a Jump Start is mounted on a Zenoah G-62. The black module at the bottom is the CH heavy duty ignition module. The item mounted near the magnito is a Hall effect transistor used to sense crankshaft position. The little blue item is a kill switch. Next to it is a battery connector.

If you buy one you will get a wiring diagram and full instructions. Once the engine is started, the 6 volt dry cell battery is removed and the engine is running on magnito. They work really good and beat the heck out of a spring starter.

Hey Big.......what did you use to take the photo of the jump start?
.Im looking at buying a digital camera primarily to transmit pictures just like this cause its so much easier than trying to explain verbally.
I dont know whiz about cameras so can you tell me the min equipment needed to get results like yours?
Other opinions are welcome but pls keep it simple......Im a simple guy!

Thanks

Hi Kevin, you can pick up a decent camera for around $200 CDN at any Future Shop when there is a sale.

Anything with 1.2 mega pixels and 4 MegaBytes of memory wil do fine.

Thanks NR......

Yes it would but you should do some reseach regarding the other models in the store so that you are making an informed decision.

If your requirements are low to moderate this camera should do fine. Also, look for an AC adapter or rechargable batteries to use when uploading pictures to your PC.

Hello - try
www.dpreview.com
check out cameras on left hand side, then pick brand, then model.
Bottom of each Brand page also has discontinued/past models.

In-Depth reviews average 20 pages each - most superb reviews site I've seen on cameras. Rating systems, reader reviews/ratings etc etc....

I bought a Canon G1 last year and am quite happy.

Kevin, here's a link to a site that'll bring you up to speed when trying to find just the right digital camera.......

Tkg, is there a way to make the Jump Start usable on the Fuji BT 86? I have one that I used on my Z445 which is no longer in use.

Tks to all who answered my camera question.....sorry I screwed up the jump start thread.........

Kevin, you didn't screw up the thread. To answer your question, that photo was made at rather low resolution (640 x 480) with a Panasonic camcorder which has a digital photo mode. I currently use a Canon S-100 Digital ELPH shirt pocket size camera with 2 megapixel resolution. It has 64 megabytes of memory and I can get about 100 high resolution photos before I dump it to the computer. Most modern digital cameras use a USB bus connection to download JPG format photos to your computer. Make sure your camera is compatable with your computer. The previous digital camera advice in this thread has been very good. Of all the accessories that I've bought for my RC hobby, the digital camera has been the most fun. All of the photos in my gallery were taken with the Canon.

Jump Start
If you want to know if a jump start will work with engines other than the ones tkg listed, just drop him a note.

Sorry not yet. But hang on we might figure it out.

I think what tkg meant by "secret" is that the requested schematic for the Jumpstart is proprietary to tkg (CH Ignition).
Only fair since they developed it and should reap the financial gains from it, correct?

captinjohn, INJUN_EAR is correct on the proprietary stuff. Intel doesn't share internal information on computer chips and Coca Cola doesn't publish the formula for Coke. On a smaller scale, but no less important, is CH's design of their ignition systems. This is a business to them and not a hobby.

Capacitive discharge ignition systems have been around for years. In the simplest terms an oscillator runs and is used in charging a capacitor which supplies voltage/current to an SCR. The SCR then is triggered to produce a current pulse into the primary of the high voltage transformer which in turn produces the spark. This is a simple concept but the technical design is what sets one system apart from another. I'm sure if you go to your local library, you should be able to find an EE type text book that will have a chapter on the subject.

Actually what TKG means is there is no schematic. The circuit has been refined for over a twenty year period by the "what happens if" type of engineering.

There was a schematic published about 10 years ago in MAN if you want to find it and do your own

Hi have you found out any information on your ignition system? If not write back , I am also working on installing a ing. system on my old weed eater. mit be able to help glenn
