Yes they make expensive testers that can check a condenser, but who wants to buy expensive testers to test what is really obsolete technology?
a) Check all your wiring(real minimal with a mag).
b) clean the points simply using a piece of brown paper bag. Even a hint of oil on the contacts can cause issues. File the points if needed, but I try to avoid filing if possible. Reclean after filing and finally gap the points to spec.
c) Try starting or check for spark
d) If still no spark then for mag equipped then I disconnect the kill switch wire to insure that switch is not always shorting out to ground which is how a mag equipped motor is turned off. If a distributer, then use a piece of scrap wire to jump the switch to insure continuity across the switch.
e) If still no spark then replace the condenser. I keep a small assortment of old used condensors that my dad had saved over the years doing his tune-ups. I stick any old used condenser in there from that known to be good bucket that will fit. If the tractor starts, then I immediately cut the wire of the condenser that I removed and put it in the scrap metal pile so I can never grab it again by mistake. Then I go purchase the proper spec condenser for the application and install it (when time permits). If you do not have a known good used condenser to temporarily put in then just go buy one at OReilly's for $9.95 plus tax. I just put one in my Farmall H (dist ignition) less than a month ago and they have a lifetime warranty to boot which is rare on electronic parts. Ironically the tractor ran just fine for a couple weeks on my temporary used small block chevy condenser - LOL. I would recommend you look up the part # yourself on BWD website (not OReilly's website) as untrained staff may not be able to look it up for a tractor as they often lack the catalogs.
f) If still no spark well then it gets more involved.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
