I just received my switch last night and have two problems with it I wanted some feedback on before I talked to mfg. This switch has no ground wire. I have been told that a ground wire is an absolute necessity on the MVVS 1.60 Gasser. My biggest problem is the switch itself. The bar that plugs in to shut off the power has no friction, what so ever. It is completely loose and only sticks into the housing about a little less than 1/2 inch. It will fall out at the slightest jiggle or if the plane is tilted over. anyone else have a problem with this. thanks.

The Fromeco switch has a ground wire where it needs one... in the shrink-wrapped part. The "switch" part you are talking about doesn't pass electricity to the RX (or ignition module in your case). Matter of fact, you can cut off that wire and power and ground will still get through (part of why it is called failsafe).

As far as the pin being loose... try pushing it in a little harder. After taking the pin out a few times, it will get easier and not take as much force. I went ahead and doubled the gluing surface-area on the holder... just to be safe. The holder in the pic below is a carbon fiber and 1/64"-ply sandwich. Light and very strong and gets glued to the inside of the fuse.

I hope this helps!

Hi Spais,

I'm not sure what your ground wire issue is. No switch will have a ground wire for an electronic ignition. The switch should be used to interrupt battery power to the ignition and that's it. Can you send exactly what your manual says. Typically you do have to ground the ignition, but not through the switch.

As far as the loose pin, it's one of two things: one, you have a bad switch, and two(which is what I think it is, since I did it too), you aren't pushing the pin in far enough. It takes significant pressure to seat the pin. It is a very tight press fit.

**Oops, looks like Andy beat me by a couple of minutes. At least we seem to agree.

OK, you guys were correct. I was not pushing the pin in far enough. As far as the ground is concerned - I will have to check on that. There is a ground required somewhere between the engine, switch and the electronic ignition. Its incorporated in the switch assembly that Pe Reivers sells (MVVS Netherlands). He is very helpful and amybe between FROMECO and Pe I can get it figured out.

Maybe one of you can simplify this for me a little. this "switch" is just going to go between the battery and the electronic ignition. Correct? I.e., Battery out>switch in>switch out>ignition. the other wire lead on this switch is for charging the battery. thanks again in advance.

Splais,

>>this "switch" is just going to go between the battery and the electronic ignition. Correct? I.e., Battery out>switch in>switch out>ignition. the other wire lead on this switch is for charging the battery.


All correct.

If MVVS's electronic ignition unit has no ground wire; how do I ground it using the Reliaswitch instead of the one Pe sells that incorporates a ground. I really like that Reliaswitch, but am stymied by the grounding issue.

Hi Splais,

>>one Pe sells that incorporates a ground

If the switch has a wire to ground, then it has to be grounding something that's coming from somewhere. Did the engine come with a wiring diagram? If it did, can you describe it, or scan it and post if you have a scanner?

I think your best idea was to write Pe and ask him. I've heard he's really helpful and he could give you the correct answer in a second.

I beveled the edges of the pin that goes into the switch, that helps it separate the contacts.
