DaveSIIA Posted October 1, 2009 Share Posted October 1, 2009 Have you had a look on the Curtis Instruments web site for a manual for the controller in question? It could help identify the technology used in the duff controller - most probably power MOSFETs or IGBTs driven by a pwm chip. If replacement is too expensive, you may be able to effect a repair by a bit of detective work and cross referencing with a good parts book. Alternatively, a trawl through that well known auction site might throw up a working secondhand unit. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted October 1, 2009 Share Posted October 1, 2009 I dont know how the price compares, but 4QD are the guys you want for motor controllers! Quote Link to comment Share on other sites More sharing options...
Night Train Posted October 1, 2009 Share Posted October 1, 2009 Someone at the battery Vehicle Society may be able to help. The forum is a little slow moving but someone will respond. Alternatively look at DIY Electric Car forum. It is over the pond but there are also UK and European folks on there. Quote Link to comment Share on other sites More sharing options...
simonr Posted October 1, 2009 Share Posted October 1, 2009 4QD make the best controllers in the UK. They are not too bad value either. Now, I might just have a Pro 120 kicking around: http://www.4qd.co.uk/prod/proMk2.html Can't remember if it's 24 or 36v - but they are easy to convert. If you are interested - make me an offer. I've kind of moved on to bigger things - 1000A at 220V Si Quote Link to comment Share on other sites More sharing options...
