Temperature Bulb / Capillary Tube

[Emma-Knight]

Does anybody know if the capillary tube gets hot, especially behind the dash? - With other words: are they dangerous to cables? I had a few cables with small areas of black distortion from outside. Not the "melted" wire look, more like burned from outside.

Anna,
I don't think there's any issue with the capillary tube getting hot enought to burn your wiring. I would think there's a greater danger of wiring getting burned by too close proximety to a hot engine or exhaust tubing under the hood (bonnet.)

Looking at the back of what appears to be your ammeter, the DPO of my car apparently wrapped the rear attachment 'clip' in rubberized electrical tape to avoid the possibility of a potential, and unwanted, circuit between the two heavy gauge wire mounting points there. Since they're so close together, I could see where that might happen. Not a bad idea I think.

No risk. The capillary can not damage the cables. My cabling is at some place tied together with the capillary tube and it never damaged the cabling.

Thank You boys. I'll have an eye on the ammeter. The DPO fitted it so close to the heater box. Looks nice on the front. It still might have to come out. And lovely original teak would need to be recovered. It might work when all "felt-spacers" are fitted correctly. I removed 14 cables, dead wires, paralel fuses (a paralel line, one fused one not - and nice cuts in the original cable to do the paralel thingy)and cleaned and resoldered connectors. Hope I'm on the road before snow...
