For my first post I have a problem
I bought a second hand eq2 mount of an upgrade to a cheap telescope. It looks like a single axis Skywatcher type. I checked the controller and drive were working. Later on I plugged it into my variable powersupply in my car without first checking the voltage. I put 12v though it and toasted something in the controller. I'm so grumpy at myself.
It's not worth having professionally repaired. I think I shorted out a couple of the transistors since two of them get quite warm when I plugged it into the correct power. Also they are reading no resistance on the multimeter. I'd like to try and repair it myself but I don't know where to get PCB components, don't know a lot about using the multimeter for diagnosing but follow instructions well
and can solder OK. I was hoping to get some help, either online or in person as a little weekend project in exchange for a slab or a bottle
thanks
