'77 FJ40 - Gear Reduction Starter & Dizzy Upgrade (1 Viewer)

[jbldaddy]

Did this upgrade last night, what a great difference. Timed it, took 24 minutes including putting tools away and washing hands. Great mod, thank you for all the great write up's.

Thx all for inputs and advice... waiting a little warmer weather to get this installed. GA Arch. does the white female connector in your photo also fit the connector on the new starter? Or did you put on a new connector?

Bill - I have not installed my new GR Starter yet. I believe the BW Ignition wire, with it's female connector is a plug and play on the new GR Starter, but not 100% sure of that though.

Maybe someone else who has installed their GR starter could verify this?

Yes it is, simply plug-n-play.

@GA Architect Rick - thanks for this thread. I just did both upgrades and your wiring diagram make them easy. Now to figure out how to get back the rpm gauge. I think was was hooked up to the igniter

Tachometer will generally just connect to the negative side of the coil. Thats how mine is connected. If you have an FJ60 I believe there is a resistor that needs to be installed if using the factory tach, I have seen that referenced elsewhere in the forums here.

Thanks. I figured that out after I posted. All good now.

Spike - It is that thread that prompted me to draw a diagram. I couldn't figure out Mr. Toad's post #64 from that link, back in 12/2009. I couldn't follow along his written directions, and I wish there was a schematic wiring of that switch. So I kept searching. Then I happened across this from Mr. Jim C. on the thread, see post #2 from 5/2014. It was a much simpler approach.

Mr. Toad adds a switch & Jim C. caps off the coil wire to the starter...............Are these both right or does one supersede the other? Hence this thread.

If adding the switch is correct, send me a wiring diagram and I'll update my original post........

85 - +12 volt in from..."brought up from big BW on small BW".....That is the statement I don't understand.
30 - comes in from 85
86 - goes to ground
87 - goes to (+) of coil terminal

What connects to the starter?

Old post, but post 64 says to run the small BW wire from the starter area to the relay pin #85. The wire supplies full voltage to the relay during cranking. It gets power (from the bigger BW wire) only when the key is in the start position. See wiring diagram below (compliments of Coolerman and MSPaint).

Worked great.

What connects to the starter? Same as before. But it's not really about the starter: the point is to supply the coil with full voltage while cranking.
