I have a RioCar Mk2a (I'm pretty sure its a Mk2a) in a Honda CRX. It has been working fine for a number of months. Then one day I noticed that the fuse for my running lights blew out. Its a 10 amp fuse. So I bought some more and put in another one. Everything seemed fine when I turned the lights back on. Then I go down the road for a minute and look at the lights. Fuse is blown again. I can't figure out what the hell is going on. I thought maybe the RioCar was putting the draw a bit over 10a so I put a 15a in to see what would happen. The 15a fuse blew just the same. When I pull the RioCar out, the fuse never blows.

Does anyone have any idea whats going on with my RioCar?
