Does this gauge have an alarm on it

Asked by: Stumps
Thank you for your question. Unfortunately this gauge does not. I would recommend looking at P/N: 5646.

Hi I was recently gifted this gauge from a mate as it was collecting dust in his garage. Unfortunately he didn't have the wiring harness or EGT sensor to go with it. What harness and sensor would suit this gauge?

Asked by: Jordo
Thank you for your question. All you need is harness #5251 as that is both the wire harness and EGT probe.

I have gauge part number 6144-m and the backlight has gradually gone dull to the point it no longer illuminates. Is the bulb replaceable or is there any sort of warranty? Thanks

Asked by: Spearsy
Thank you for reaching out to us. The white wire in the harness is what provides 12V to the illumination circuit. Make sure this is still pinned properly into the connector that plugs into the back of the gauge. Our Cobalt Series features multiple circuit board mounted LEDs and would have to be serviced if any of the LEDs are not functioning. Our warranty is 12 months from the date of purchase.
