Hi folks...

Looking at switching the WD45 I bought last fall to 12V.

The PO had it set up for 8V and the battery was pretty well shot an don't feel like investing in a new 8V battery. 

12V conversion in non-power steering applications seems pretty straight forward.

Looking at my setup with the power steering, looks like the alternator fan would be right where the PS belt comes close to the generator (looks like it almost runs between the generator pulley and the generator.

What's the solution?  Run without the alternator fan for this relatively low current  draw application? Machine up or cobble together a pulley extension that will space the pulley out about an inch from the fan?  Rig up a PTO-driven alternator?  ;) 

Matt

I've done many D-17's without an alternator fan for the same reason and have never had any issues.

If you keep the battery on a maintainer like a Battery Minder it will take a lot of the load off the alternator if it sits much between use and your battery will last a lot longer.

Keep your old generator, just get it rewired for 12 volts. I have done that with mine. A local auto electrical shop can do that, or give it to Steve at B&B.

Take the fan off, as Doc suggested. If the alternator is only going to charge the battery and run the lights and ignition, you won't need the cooling from the fan anyway.
