Hermi, so you killed your cirrus already? I was thinking of getting one.
Yeah, it's an odd one, took me quite a while to conclude it was the speedo at fault. It's the first Cirrus I've heard of thats had a problem, other than a couple of guys wiring them up wrong. Should get it sorted very quickly though, ready for next weekends SMTCA round at my local club
I thought it was the motor at the start but there didn't seem to be any sticking brushes and it turned fine by hand, I changed cells just incase and no change. I then tried the LRP speedo and it did the same as my Cirrus, lights up and leds change like you're using the throttle and brakes so I thought it was the motor again. Changed that and went back to the Cirrus and now the speedo doesn't even light up
yet it's getting the correct voltages at the right bits. Even took the heatshrink off the switch to check that was working and resoldered my schotky diodes.
Changed back to the LRP and set it up properly, it didn't go. Then realised the motor I'd put in had a brush spring missing
so fitted that and the car went fine.
I'll put my man 19turn motor in tomorrow for club racing, the Demon that I originaly had in today. It should go fine, it went when put directly on a set of four cells, but I'm wondering if the missing spring on the other motor would cause the Cirrus to not light up. I don't think it would stop it turning on, as I've put the same motor in before with no spring, it just stops the car going but the speedo does usualy work... I think
Took me over an hour to get the thing finaly sorted, missed practise and my first qualifier. A right pain in the rear.
