I'm using On Board Glow for a large engine.

It has worked well. But, a couple of times now the plastic insulator in the plug connector has melted onto the plug leaving a real mess and no connection. I've checked current (only using 1.2v), used different glow plugs and new connectors each time. The engine runs fine and does'nt seem to be excessively hot.

It does seem that normal engine heat would be challenging to plastic? Also a solder connection may melt.

Anybody else had problems like this? Any suggestions for a connector that holds up to heat?

G'day Mate,
The covers for the connectors are usually made of silicone, just like fuel tube, it is heat resistant, so it won't melt.

You can use a clip that the RC car guys use to hold the bodies to the mounts (like a tiny hair clip). Solder the red wire to the loop on the end of the clip, and tighten the clip so that it will hold on the end of the glow plug. Cut the excess off, and you can bend it if needed. No touchie, no shortie.

An engine should not get hot enough to melt solder.

Solder a piece of wire to a wheel collet and clamp the collet on the plug.
