I am nearing the final assembly stage. I cannot get the fuel and temp gauges to work yet. I must have fried the little voltage regulator on the back of the speedo, so I replaced it with another, and it fried too. I put the new regulator on, the fuel gauge maxed out, then blew the regulator. Can anyone tell me if it matters which side the wires hook up to, they seem the same. What should the volts be on each of them? I have tried everything and those little regulators are not cheap. Any suggestions? Thanks.
