Buckaroo Posted August 18, 2018 Report Share Posted August 18, 2018 2007 CTSW 770 hours. Starts every blade until this morning. Been two weeks since flown. Went out this morning to fly and cranking only. No pop or fart just turning with choke and noto choke. Yes it has both oil and gas! Any ideas? Hope it not the two $2k ignitions! Thanks!

Roger Lee Posted August 18, 2018 Report Share Posted August 18, 2018 The absolute first thing is to rule out a poor battery EVEN if you think it is okay because your human ear can not tell the difference between a few rpms that will start vs not start. Jump it from a good battery. Jumping a battery is free and easy so do it. Once you know the battery is good and it still won't start place a 1 gallon baggy of ice around the ignition modules. Don't make it too full because you will want to wrap this around your ignition modules on top of the engine. Let it sit for about 30 minutes and try to start again. If it cranks right over buy new ignition modules. You can if you like send the modules you have into Lockwood and have them tested if you want.

If it’s the modules is that the $2000 part or can one get these cheaper? Link to comment Share on other sites More sharing options...
KentWien Posted August 18, 2018 Report Share Posted August 18, 2018 I had the same problem. For me, it just turned out to be the battery. Odessey battery was about 6 years old if I remember correctly. Link to comment Share on other sites More sharing options...

Odessey battery was about 6 years old if I remember correctly. I just went out to the hanger and put another very charged battery to her with the same results. Tomorrow morning I’ll try the ice. Can anyone explain what the ice does to the ignition modules to let it start? Thanks Link to comment Share on other sites More sharing options...
Anticept Posted August 19, 2018 Report Share Posted August 19, 2018 It's a starting circuit peculiarity. Ice makes it work. Link to comment Share on other sites More sharing options...

FlyingMonkey Posted August 19, 2018 Report Share Posted August 19, 2018 Yours is acting like mine did. Most often when the modules fail, they won't warm start without ice. Mine was opposite, and wouldn't cold start without heat. Since you are having cold start issues, before the ice trick I would try hitting the modules with a heat gun on low or hair dryer for 30 seconds. If that doesn't do it go to the ice. If it is modules, fingers crossed it's just one bad one. Link to comment Share on other sites More sharing options...
Roger Lee Posted August 19, 2018 Report Share Posted August 19, 2018 Just pop them off and send them to Lockwood if you want to be sure. Link to comment Share on other sites More sharing options...
Buckaroo Posted August 19, 2018 Author Report Share Posted August 19, 2018 Ice test today soon! I’ll advise as to the results. Thanks for getting me here to perform the test. Link to comment Share on other sites More sharing options...
Buckaroo Posted August 19, 2018 Author Report Share Posted August 19, 2018 Ok back from the hanger. Went back with a big bright flashlight and saw this: If you look between the heat wraps you’ll see a tiny white disconnected wire. That should go on the upper shrink wrap and is probably a wire to eliminate radio interference etc. I put that back in place and iced the ignitions. Walla she starts. Let the system go back to room temp and she still starts ever time. I waited two hours and she starts. Question: When I uncoupled the main connection from the ignition to fix the wire did something happen that now cures the problem? Who knows I guess but since she is starting normally should I leave it alone? Link to comment Share on other sites More sharing options...
Tom Baker Posted August 19, 2018 Report Share Posted August 19, 2018 The normal thing is that you ice them and it starts, and it will continue to start like normal the rest of the day. Come back and try it tomorrow or next week and see what happens. That will be the true test. Link to comment Share on other sites More sharing options...

Now what?? My problem started out very intermittently and then became more frequent. I'd send both modules to Lockwood for testing. Link to comment Share on other sites More sharing options...

Now what?? The way I see it you have 3 choices. Go until you have another issue and do further testing, pull the modules and send them to Lockwood for testing, or just replace them.

Yup you’re correct Tom and your 3 choice listing will be the order of how I will handle this! I called Lockwood and learned that these ignition modules can do all kinds of crazy things over a extended time when failing. I think the short answer is to pop em off and send them in when suspecting trouble. Im going to give mine one more chance before I send them in. In the mean time I’m putting more money away each month for the inevitable problem. Link to comment Share on other sites More sharing options...
