Now I've finally got the cooling system back together and think I've sealed up all leaks. I'm back to the issue with the gauge, sensor, etc. I've been switching out different sensors and voltage stabilizers without much luck. The last time I was messing with it I noticed the blue wire from the voltage stabilizer was loose. upon further inspection, it came off of the circuit board. I believe that the wire may have been coming off all along. Would that cause the gauge to malfunction if the connection was poor? I'm going to solder it back on, is there anything I should know before doing so? I'm not very skilled at soldiering.
