I purchased a KOSO cylinder head temperature gauge from SIP. I have an AC system so purchased an Intelliconverter from Scootronics to power it.
The Intelliconverter is powering the gauge and is working as I can charge my iPhone from it. The backlight on the gauge is working but I am getting no readout from the gauge at all. You have to hold the button down for 3 seconds and it should then burst into life. It doesn’t.
I have checked the continuity of all the wiring and it is all good.
I’ll post up a drawing of the way it is wired in a bit but, for now, is there any way of checking whether there is a problem with the gauge itself? It could be that this gauge is fairly old stock as the internal battery it came with was dead. I had to buy a new one.
The sensor. I broke the first one in fitting it. I have fitted a new one.
