Smoked My Quda

I gave up on the svelte null modem and velcro'ed in my trusty DB-25 pin chain-o-cables for the E-meter, and proceeded to put on the covers, rear fairings and tank in record time.

To top off this "release", I decided to put the recommended 41 psi of air in the tires. All the good bicycle pumps I own use Presta valving exclusively, so I decided to use the old 12 volt air compressor with its cigarette lighter ends, plugging it into Tronbikes never before used accessory port.

It worked great, I was headed to bed before 11pm. After all the pumping, maybe 10 minutes of runtime, turned it off and then tried turning on the bike. I got a flash of green on the dash then nothing. Dead. Removing the seat, I checked my line into the DC-DC converter and found a blown 7 amp fuse. Odd since it ran the pump no problem.

I put another fuse in, no green flash just another blown fuse. I noticed a wire tight under the tank, removed the fairings and tank. Another fuse, boom.

I disconnected the harness from the dc-dc and swear it registered a sane 13 volts. I poked around for a short circuit, deciding it might be the bulb itself in the dash. Tore off the covers, removed dash, checked lights, all looked sane. Boom, another fuse.

I was out of fuses, so I canabilized the 1 10 amp fuse from the accessory loop, put it in my main chain to the converter where I'd been blowing fuses. No more blown fuse, but still I had no 12 volt accessories. I then checked to find the DC-DC dead, despite the 63.7 input drop.

My theory is I blew the DC-DC converter ($25 Quda) with the 10 amp fuse, and/or it was going before then as its only rated for 20-60volts input. Something in the ignition could be bad too, dunno, but I need a new converter, a wire labeler, a ton of fuses and a wiring diagram and then go on a short circuit hunt.
