Potential hazards
 

I recently set up a new glider and was using some "used equipment" I was having difficulty charging my 750mil NiMh pack that I had been using with good succes in another airplane. My SuperNova would only put in about 75-90mil amps and stop charging. I took the battery out of the airplane and hooked it directly to the charge cord and wallaaa, it charged as usual.
I hooked up the battey again to the setup and this time I hooked up my expanded volt meter to check things over. A quick wiggle test indicated a partial open or grounding problem in the switch leads. This is not the first time that the expanded meter has saved me from a potential problem/crash. The SuperNova was also telling me there was a problem also. Also wiggle test all your connectors and watch for flucuations in your meter. Tell tale signs you have bad conectors or wiring problems
Just some FYI to prevent a problem. Seems the switches are the most problem areas I have had to contend with on most of my stuff... so I go with the upgrade ones when ever possible.
