Having some problems getting a 2nd hand RC18T up & running... bought off the bay, pretty good / lightly used condition. Couldn't charge battery straight away as it looked like the chrager connector had been wired incorrectly, and before I connected it to the battery I needed to buy a volt meter to work out for sure which wire was positive. OK, so done that and this threw up the first question:
HPI charger states output 7.2v and 300mah, yet volt meter was reading 13v...????? Any ideas???
Anyway gave it 4.5 hrs (1100mah battery), put it in car, turned on... and nothing.... so, connected volt meter (difficult as it had a mini-t connector so could only just get end of probe in to holes), and it read 0.35v... OK so battery looks ****ed, well might as well cut plug off and use for some soldering practice before fitting deans on a new battery. After doing this I noticed that the copper wire in the negative cable was completely black... all the way down the wire... yet the positive wire was still a nice copper colour...
Before I go any further, can anyone suggest what might have happened here??? Could the previous owner have done something stupid with it and fried the esc as well???
