The original controller for the first generation LectraSan was a "stove timer"-like controller. The user flushed the toilet, the started the treatment cycle by turning the dial to the start position, which was--and still is--a 2.5 minute process. For the first 30 seconds, only the mixer and macerator runs...then a relay kicks the treatment cycle on for two minutes and then shuts it off. It's a 12v gadget for which there is no existing substitute. Raritan discontinued it in favor the EC (electronic controller) version, finally stopped supporting it in the early 90s. Frankly, I'm surprised there are any left that still work...or maybe he just bought the boat with a geriatric LectraSan that came with a non-working controller. The only person at Raritan who knows how repair the old dial controller or cobble up replacement retired several years ago, so unless somebody who's done it turns up, he's gonna have to come up with a different plan. I don't know whether it's possible to retrofit an MC (microprocessor controller that was the successor to the EC version) controller to a treatment device that old, but that MIGHT be one option.

Meanwhile, I'm kinda having fun doing a little work again. But I'm pretty sure that'll wear off soon.:)
