I had to put a remote glow plug lead on my Model Tech P-51 with Saito 72. The engine just barely fits in the engine compartment, making it a bear to squeeze a glow igniter directly onto the glow plug at the head.

So, I bought a Sullivan remote glow plug lead and hooked it up. Well, when the glow plug is in the engine head the cap that connects to the plug is really loose, not allowing current to flow to the plug. But, when I take the plug out of the engine head and put the cap on it fits tightly.

Does anyone know any tricks to get this darn thing to work? I'd like to put the cowling on this bird but can't while I have this problem. Thanks a bunch!

sounds like it is being kept from seating by interference with the head.does the tip of the glow plug stick out above the head?if so make your own connector by taking a 1/16 whell collar and soldering a flexible wire to it.secure this to the center lead of the glowplug by tightning set screw till tight.solder another wire to a washer under one of the engine mount screws .attach these to your onboard battery or rca type jack

You could try trimming the rubber "cap" of the glow plug lead.

Hey Paul,
I'll bring a glow plug lead with me tonight. The kind I use are like a spark plug boot that seals tightly over the glow plug and the terminal part of the lead has a good, positive connection. I'm not sure who makes it, though. 7:00 Dave

The cap is made of some sort of metal, I can't remember what metal offhand. I would try making my own but my soldering skills flat out suck! I may have to give it a shot though.

What about putting a spring inside the cap? Do you think that would work?

Hey, right on Dave, I appreciate that! See ya at 7. Later.
