I want to add to this post something I ran into yesterday.... I have an old power panel that I use on my remote connection for the in cowl glow plug and I could not get anything to work/glow... Today I installed my new one and guess what everything started to work/glow... It seems although my old panel worked in all functions ....it did not have the full power needed to cause the glow plug to glow... I am checking that battery on the old panel and will report back later...

So be sure you are getting the correct power/voltage to your remote... use a volt meter and check yours and others at the flying field... It could be either a battery problem or the power panel that is not getting the correct power to the glow plug...

Also, if you are using the power panel to provide power to your hand held starter it can deplete the power supply enough to cause the glow plug to not glow.... ( if both are being used at the same time and that would be normal when starting)....

I am using a different power supply now for my starter but did have that problem of voltage drop to the glow plug last summer when using the starter and the glow and the same time....(you will see the needle on the panel drop when cranking)....
