Gday, have done an archive search but can't find anything to help. Any advice appreciated.

I recently bought a VDO exhaust temperature gauge but the damn thing won't work. I have bypassed the wiring through the ignition and connected the dial directly to the battery using a 5amp in-line fuse. The light works perfectly but the dial doesn't move.

The thermometer fits into the headers by means of a small hole drilled into the headers, hose clamp with thermometer holder welded to it.

Where would the problem likely to be?
How would I test it to find the problem?
I have followed the fitting instructions except for bypassing the ignition. I can't see how this would effect anything, it's still getting power from a 12v source and is fused.

Any tips appreciated.
