I thought the very same thing - that there was a connection issue on J2-5 so I removed all the solder from it and the 'circle' is still there underneath it all. So there does not appear to be anything obvious (to the magnified eye) there. I soldered it back up and still no continuity, and thus the ...

Problem solved. I managed to find a via between R10 and J2-Pin 5. A jumper wire between J2-Pin 5 and the via resulted in a completion of the circuit and proper coolant temp sensor display

Conclusion - there is an issue between J2 Pin 5 and the rest of the circuit on the Microsquirt Module.

OK, there's a via right under that CPU pin (half way between C13 and the CPU) and I can see the trace from the CPU to that via so I am sure the via is correct.
There is continuity between the CPU and that via but there is no continuity between the via/cpu pin and the Coolant Temp terminal on J2
R11 ...

There's a method to my madness.

My coolant gauge in Tuner Studio stopped working. I have continuity all the way from the sensor to the top terminal on the Microsquirt Module - so it should work but it doesn't. This leads me to believe that the problem must be before the J1 terminal on the ...

Hi!

Is there a via somewhere on the board that I can tap into for access for the CLT/AD2-1 Input?
Also, while I'm here, is there via that I can tap into for access to ALED ?

Thank you Mike - appreciated!

Can anyone confirm for me that the Microsquirt Module is actually 61 mm X 89 mm ?
