Does anyone have any of the old Cox glow plug clips in your junk drawers? The kids seem to like them the best (but I like the hinged type better). I make them up with two D cells, as shown in the photo, and give them to the kids.

Got one, but wires are only 1” (short). Will fire it off in the mail to you.

PS

I find that these only fit the older glow heads. OK for new heads if you trim back the shoulder of the head with a thin rotary tool grinder disk.

    On any  of the older Cox glow clips, the wires can be of some suspected quality. I have sent some off to various people over the years and got reports back that they didn't work. Turns out that the copper wire in these can corrode and not carry any current at all. They may show continuity with a meter but won't drive a glow plug. I have personally witnessed some that did not light a plug, but when another plug clip was attached off the same battery, they lit up nice and bright. They should come apart and just replace the wire with some better quality stuff. i notice the one in the photo has two red wires. Most I have ever seen have two colors, red and blue I think. Maybe these were changed out by some one?? I have emailed back and forth with Bill Bischoff about this I think, after I sent him a couple. Some may not work even if new and fresh out of the bag.

I always take them apart to strip and solder the wires, adding heat shrink for stress relief. I recently had 3 new ones, still in their package. Of the six wires for the three connectors, only one wire was making connection before I remade them. They were built with the copper straps only crimped over the insulation, instead of stripping the wire. But were fine after I remade them.

There is definitely such a thing as Bill suggests, normally called an IDC (Insulation Displacement Connector), but the piercing elements don't look like the photo of the Cox clip. The picture looks like a case of manufacturing processes getting out of hand due to either lack of training or damaged/missing tooling? (And no inspector, either....)

I was out flying today with a new guy, and we were using a Beginner's Ringmaster. My expensive glow driver wasn't getting it done, so had to resort to holding a DuBro ignitor on the glow head of the super-powerful Baby Bee. At least it was charged up and popped the engine right away....
