CH Electronics Syncro Spark Temperature Tolerance
CH has discovered a possible temperature sensitivity problem in the Syncro Spark timing board. One of the electronic parts on the board may not meet its design temperature specification
The symptoms are the ignition will start to fail when it gets hot. The engine will restart when the ignition cools off, but will stop when it heats back up.
We have determined that the affected ignitions are part of a particular production run. This run affects ignitions sold between Sept 2002 and June 2003. CH ignitions should be marked on the back side with a month and year made. Example SS OK 01/03 BC
Even though most of these ignitions are out of warranty CH will replace the Syncro Spark board in these units. The ignitions will be repaired and returned at no charge. Contact CH Electronics for details.
We at CH Electronics are sorry for any inconvenience this causes, but these repairs must be done to ensure that all of these units will meet CH Electronics standards.
This does not apply to non Syncro Spark units for engines with mechanical spark timing

syncro spark
tkg, just received a ignition module yesterday that you folks repaired under warranty for me. Loved your tuner around repairs
it was really quick.
My question is is the ignition supposed to discharge to the spark plug when the kill switch is turned on because mine dose now and it didn't before. I have only one run one this module. It still discharges when you turn prop over.
Wondering if something is going bad again already?
Thanks again

Just the module heating up or does it have something to do with the air temperature also like in the high 80's and 90's
I've got two in that time you posted, but haven't had any problems with them.

If you, or anyone, has a CH Ignitions Syncro Spark unit built in the time frame that tkg noted, it is best to send it in to be checked. Better now than after a dead stick landing on a hot day.

This is why I like doing business with these guys. A lesser company would quietly fix the units customers send in complaining of deadsticks, while they publicly deny having a problem at all.

CH Electronics Syncro Spark Temperature Tolerance
This week my f.p.e. 3.2 with CH syncro spark quit for the first time. I went vertical after take off ( do this all the time ) got 80 to 100 ft before it suddenly quit with no warning. Just last weekend i read the posts about some problems your having but my unit falls out of your target dates. It is dated 04/02. Could the problem go back that far or do i look elsewhere for the cause? I purchased the engine last fall, built over the winter and have been flying it this season with about 7 gal. through it so far. By the way, the plane (waggstaff 300 ) did a nice tail slide, fell past the vertical down line buy about 20 deg. to the inverted side and i couldn't get enough speed to pull out into a glide or flare. Came in very hard on the gear and snapped the whole nose off. Didn't even crack the cowl though. Wish i'd just pulled out inverted and rolled over. O well.

Follow the trouble shooting guide. Check for pluse switch, ignition switch, battery, broken wire type stuff.
The "problem ignitions" start running ratty, then will not restart.

Not good. The ignition will draw about 400ma. So that v will be even lower when the engine is running.
Can you cycle it from this point and see how much juice was left.

Ignition stopping
Is there a way to cut out the ignition without cutting the supply voltage to the unit?
For reliability purposes I don't like running the supply voltage thru a switch

Ya gotta to have a switch between the ignition and battery. Even with the engine off the ignition is drawing 30-50ma. So you need to turn the ignition OFF

The ignition on my BME 50 is dated 04-03. Should I send it in even though it hasn't given me any problems yet? How long does it take to fix it?

ON one hand is the cost of postage and a lost weekend of flying, on the other hand is the cost of a lost airplane. Your call
We normally get in one day out the next on this warranty action.
If you are willing to call and remove the back I can tell you what to look for to see if you have one of the units that need to be recalled.

RE: CH Electronics Syncro Spark Temperature Tolerance
I have one that went bad.Luckily it just stopped working on the ground.Use another ch that someone had at the field in my plane and it fired right up.So that being said I'm sure these recall ignitions will fail.Not if but when.So send them in.I have a lot of money in my plane.So I'm not risking it!!!

RE: CH Electronics Syncro Spark Temperature Tolerance
I will third that! I sent in my CH ignition to be upgraded and the turn around was less than two weeks. Most of that time was spent in the mail going back and forth. I highly recommend CH Ignitions to anyone & everyone. Quality & Honesty keeps happy costumers coming back for more with new customers.

RE: CH Electronics Syncro Spark Temperature Tolerance
More bad ignitions than the dates posted. One on a 3.2 FPE 050704, one on my H9 Sukhoi 5.8 FPE 050904 and one more on a Zenoha conversion 050604. Mine just failed today and the is no way it was heat related. 71 degrees outside and the engine would just not start. Grounded the white wire going into the ignition still no spark. Will be sending it in for warrenty. The other two planes landed deadstick.
