P mags and more
Well it's me again. I have not had a chance to try the updates to the E/P mags lately because of a new job and lot of overtime. Besides the weather in Alaska sucks, Global Warming, I don't think so, Global Weirding is more like it. Snow storms in April and fresh snow on the mountain peaks almost every week.
Anyway. I will give the E/P mags another shot this weekend. If they screw up they will be gone.
I did use the Emagiar way of wiring. I do have 2 DPST toggle switches to each mag, I did use 18 gage wire, I do have them grounded to the engine.
Now there is another service bulletin which makes me not very happy. The mags were back to Emagair twice this summer. Oh well.
Thanks for all the great updates and vendor bashing.
What fun!
Mike

P mag dead again
I went to the airport this evening to go for a short flight and started the engine. The engine did not sound right so I performed a mag check. When I turned off the p lead to the p mag there was no rpm drop, When I turned off the power to the p mag there was no rpm drop. When I turned off the p lead to the emag the engine died. The switches to the p mag had been returned to the on position.
I really think emagair is onto a great product but I can't seem to make them work for me. Maybe I am just too old school, or too old, whatever.
I will be removing the p and e mag this weekend for the last time and replacing them with slicks this next week. I don't think the slicks are as good as e/p mags are or someday will be but no one up here understands how to make them work including me. I do know traditional mags and I can make them work and almost every a&p mechanic anywhere knows how to repair them.
I really don't know what I will do with the e and P mags. I guess I should return them to emagair for the latest SB and try to sell them. At least if I get the latest fix then the next person that gets them might have better luck.
Really, I don't have any hard feelings towards Emagair or their product and I am not going to make this personal.
Any tips or ideas on selling the mags would be appreciated.
Scattered snow showers are expected this weekend and I want to go flying before real winter gets here. Maybe next weekend after the slick mags are installed I will but in the mean time another weekend has been lost to the e/p mag puzzle.

Emag power
Mike,
You can't kill the power to the Emag. The engine will die if you also have the power to Pmag shut down. The Emag is power dependent.
No offense meant here Mike, but something is AFU in your install, wiring, or something. It is just unimaginable that you could have so many problems after having the units replaced and updated so many times.
I'm at a loss and wish they had worked for you. Before abandoning, I'd completely rewire everything. There are only a few wires and shouldn't be much harder than R and R of the mags several times. At least then, you could have piece of mind that you've tried everything.
I hate to see you invest in a complete new system only to discover there was some other issue unrelated to the Emag Pmag.

maybe my wires are crossed but
Darwin,
All my problems seem to actually be just one problem. The P mag doesn't seem to work all the time.
While performing a mag check on the Pmag I turned off the p lead noted the rpm drop, none, then turned the p lead back on. Then I turned the power off and noted the rpm drop, none, then turned it back on. After that I turned off the p lead to the emag and the engine died. This seems to mean to me that the pmag had never been on right from the engine start. Yes I know that if you turn off power to the emag while the pmag has no power to it the engine will die but there was power to the pmag, well at least the switch was on.
Your suggestion to rewire the mags is a good one and given different circumstances I might agree but when I do rewire it will be to use the Slick mags.
I would reallllly be upset to completely rewire the e/p mags and have the same problem happen again.
I want to go flying.
Thanks for your advice just the same.

Just curious
I'm just curious if you have checked your wiring with a multimeter. I have to agree with Darwin. I think something is AFU. I've been flying P/Emags for >250 hours. I updated twice to newer models and now have 2 Pmags and they work great. I've only had a problem once when a magnet came apart. I find it near impossible to believe that you still have a bad PMag after all the updates and repairs. Good Luck.

wires AFU
Charlie,
I have checked my wiring with a multi meter. I have checked for loose wires. I have checked for frayed wires.
But... I agree it could be my wiring. Ok. no big deal, it may be AFU as you suggest but FIIGM slicks on order.
Hey, I admit I am technologically challenged, I don't even own a cell phone. I don't have an HD TV. I have a cabin that has no electricity and no running water and we use an outhouse and burn wood in a stove for heat but the view from the front door looks out over 2 mountains ranges and one truely magnifcent glacier.
I like to keep things simple and for ME the E/P mags have not worked. Why isn't as important to me as that they do or don't. Just a personal choice thing here.
I am not bad mouthing Emagair. I still think they have good products and GREAT customer service.

Frustrating
Hey Mike,
I had to laugh at the technology challenged comment. I'm with you on that one. I had good guidance and took it slow. Knock on wood, no issues in 400 hours.
I wish you were close, I'd love to have a go at your system. Stuff like that becomes personal. I commend you for your perserverance.
Please let us know how the Slicks work out. If they don't work, make sure family member remove all sharp instruments and firearms from your access.

checked again
Darwin,
I went out to the airplane today and checked the entire wire system and switches for the P mag. All of the wires and connectors tested fine with a multimeter and swiches were doing what switches are supposed to do. I checked to see that power was getting to the p mag and it was. I took out the pin connector from the p mag and checked all the wires to it as well for tighness and loose strands, they were all ok. I made sure the ground wire from the p mag went to and engine bolt (unlike what Mr. Knuckols suggests at the firewall ground)
When I started the engine, it started great, it ran just fine, so I did a mag check on the p mag, standard practice, p lead off then on noting no rpm drop. At that point I was sure the p mag wasn't working as usual but I tried the self powering function of the mag at about 1200 rpms, power switch off, no drop, power switch back on.
So I then turned off the p lead to the emag and the engine stopped right away. I knew it would, but I had to prove it to myself.
The p mag is dead as far as I can see. Why? I don't know.
Anyway, I just wanted to give them one more chance. I am sort of considering the possibility of getting another emag seeing as the one I have seems to be the only thing driving my plane and it works great.
But that seems unlikely, I have the slicks on order and will be switching them out next week. Maybe! Seems as if Unison has another SB out as well and if the set I ordered doesn't have compliance with the SB then I won't accept them for delivery.
I wonder if there is any advantage to running one emag and one slick?
