49 panhead electrical problem. Where could it be?

[fitz470@rocketmail.com]

Had her running strong for a decent ride.  Parked her and shut her down.  Started her back up about an hour later and 2 blocks away she sputtered and stalled on me.  Quick inspection showed I blew my inline fuse.  Replaced it and fired her back up.  Two more blocks down the road she sputtered and stalled again but this time the fuse was fine.  As I started riding the tail light(constant) went out so I wasnt getting any power or spark.  Put the battery tender on and Im gettin no lights at all.  Its a 12 volt system, chopper so all I have is the tail light and headlight.  Whats the easiest way to tell if its the coil or generator or maybe a short somewhere else???

If you have no lights with the battery tender on it, there is probably an open somewhere in the wiring between the battery and the terminal strips.. (or the battery has an open circuit in it.) Check the wire that goes from the battery to the ignition switch and from the ignition switch to the terminal strips.
Have you polarized the generator?
Test the battery first, then polarize the generator. (momentarily touch a jumper between the "gen" and "bat" terminals on the regulator or run a jumper from the pos bat terminal to the armature terminal on the generator - you should hear a "click" in the generator when you do it.)
If it has a mechanical voltage regulator check the contacts in the regulator.
It sounds more like a wiring problem or a problem with the battery or charging system than an ignition system issue but you can check the coil with an ohm meter. The primary resistance (between the two primary terminals) should be around 5 Ohms. The secondary resistance should be around 18,000 Ohms.
Check all your primary wires too and make sure they aren't chafing anywhere - like where they go into the breaker points assembly.
I suspect you're gonna find a broken or disconnected wire somewhere.
