Littlebeaver, that trickler...

I haven't forgotten your request for a pictorial how-to. I've actually been testing and proving the circuit over the last few weeks. Seems to be fine. I can leave it hooked up for days at a time and neither it nor the battery even get warm, yet the battery always reads full voltage even after weeks not running the bike. While this is not the "smart" circuit of a true battery tender, it is capeable of providing just enough to keep a motorcycle sized battery at full charge without damaging it.
The trick would be for other guys to rummage around and find the suitable wall transformer. Answering machines, cordless phones or any device with an output of 11-15VDC at a current of 100-250 mA. That would be one tenth to one quarter of an amp. The resistor could be found at any electronics parts store or online for less than a buck. You may get by using Radio Shack items providing they still sell stuff like that. You'd have to connect several resistors together in parallel to get the proper resistance and wattage. I could do some research to see if Radio Shack still sells that type of stuff. Their line of raw component inventory is almost nothing these days.

Wow, I almost forgot about this idea of yours...I have no doubt it works great, thank you for remembering about it.. My charging system and battery concerns are not really a concern to me much anymore because of my Alt. Conversion, However when the bike sits for any length of time without me riding it, I will hook it up to my maintainer I bought a year ago or so, I think it is really neat that you made your own though,, that is a awesome idea and thank you for sharing it....

Yeah here's one that would work fine. A little bulky being a 10 Watt but otherwise fine:

Add a wall wart and a pair of battery clips and you've got a maintainer for a fraction of the cost.

You have a TRICKLE CHARGER, not a maintainer. A trickle charger will continue to supply power even if the battery is fully charged. Over time, this will actually destroy a battery.

A maintainer, like a Battery Tender, monitors the battery's charge state, and shuts off when the battery has a full charge. It will resume trickle charging once the charge level drops again.
