Binary test for electrical bulbs

Neat trick.
If bulb is issue, run 12v + directly to bulb. If it's bright you've just eliminated the ground side of you circuit. If it's Not bright, you've eliminated the positive side if your circuit, you know the problem is on the ground.

Either way your have succeeded in cutting your problem in half.

Sweet.

Repeat at each component on the power side( ie to flasher) cut it in half again ( upstream of flasher or down stream).

Sweet again I love binary tests (cuts the problem in half each time)

by setting up an A or B binary test like this, each step you cut the problem in half.

Take the remaining circuit, find a component in the middle(ish) repeat the test, cutting itin half again..

In a few steps you've isolated it to a single component or run of wire...

It's been a busy month.

I've been busy this month, got all the lights and gauges working reliably (alot more work than it sounds like!), registered as an antique while I'm fixing her up.

Seat bracket reversal
Refreshed gauge cluster
Refreshed knobs
Built center console out of 40mm ammo can (need to add cup holders to it.)
Replaced almost all the non blinking lamps with LEDs
Installed horn (waiting on horn relay)
Painted the fender flares white
Added choke lever and connected choke cable
Connected up 2 of 4 lights on the bumper (w/ relays)

And I'm working on pulling the tranny hump so I can fix the and of the speedo

MY FJ40

So I just got my FJ 40, started working on it, I'm wrench-fu level of "Total newb"
Current goal insured registered and street legal.

So Far:
Got the Blinkers and Headlights working, all though part of it occurred "magically" when i wasn't looking, which is a sure sign it'll stop working eventually just as mysteriously (Got the running lights and the left turn signal working, wandered around looking at wires and tightening and wiggling stuff. Checking current at fuses that kind of stuff, connected up to wires to the right headlight and all the lights on the outside, except the license plate light started working,about 20 minlater whiel i was not working. Does anyone have mirrors on the walls in your shop to make this kind of stuff more noticeable?

Hooked up clutch, fabbing a clutch lever to replace the missing one on my edelbrock 1405 4 barrel 600cfm carb.

Did a seat bracket reversal to give me a couple more inches, it was easy but had to
drill new holes for the front two mounts to make it work, need to make a custom plate and get that last inch that's left.


Need to finish registration,
Fix gauge cluster lights
Fix Rear License plate light
Check front license plate light
Add a an led so I know when the ignition circuit is on or not. (it's gotten me twice this weekend)
and replace the cracked fuel filter.(for which i need more info on the engine)

Thanks,

Cal-
