No OD? 700

Hi

I'd check the relay that controls the overdrive (OD) first. These things commonly fail. If you're handy with a soldering iron, reflow all the solder and add new solder if necessary. (Ebay is also a good source of used OD relays in purportedly working condition)

I too bought a cheap 740 and that was one of the first problems with it. Pulling the relay out, I had an initial look-see and it didn't appear that there was anything wrong with the solder points. That was until one day, as I was driving around and I stuck my hand in to the fuse/relay panel to jiggle the panel to get the dashlight going that I accidentally brushed against the OD relay and hey, I could actually make the OD come on off by will! Reflowing the solder at the legs fixed things.

Now there are other possible reasons why the OD doesn't work according to the 700/900 FAQ:
