OEM coil options - 1978 FJ40

[Helipilot]

Talking about ignition stuff...If we are hit by a CME (Coronal Mass Ejection) or other type EMT event will the newer electronic distributors be affected? This fourth FJ40 currently in restoration is being built for fun and to still get around if we are hit by any type of EMT. I have queried the manufacturer of my unit but have not heard back yet.

Whats an EMT? is it similar to an EMP?

Roger... I’m a layman and am not sure I will ever fully understand the ramifications of an EMP event... or, who among us will die this year, as a direct result of the EMF that exists in, even, the older vehicles.

For the reading I’ve done, it seems like the only consensus is that, while some cars may run (or be easily reparable) post-EMP, fuel availability and clear roads will likely be non-existent.

It’s curious that one of the primary events we had to train for, at Cheyenne Mountain (NORAD), in 1970, was an EMP event.

In retrospoect, our ability to actually get to the Mountain, after an EMP event, never seemed to be in question. I wonder why..,

BTW: there are a lot of wild horses in Nevada. Perhaps the best approach to preparing for an EMP event, is to prepare for capturing and breaking a few mustangs.

The ignitors used in 78-newer US spec Cruisers have some tiny SMD components on the circuit board. To my ignorant eyes, it doesn't look like stuff that would survive a serious EMP. An old fashioned points & coil setup would be the best bet for surviving.

Danny@Solace in Solitude could you tell me the part number of the coil igniter system that came out of a your '78? I have a '68 FJ40 with a Jan 1978 2F that I picked up some time ago and now putting it back together, and not sure what was correct or would work. With the motor I got two igniters and two coil...

#1 Igniter

Coil w/igniter 19070-61070 (black label)
Igniter Assy 89620-60070 (red label)

#2 Igniter w external resistor.....this one I found is listed as 1/75 to 3/76

Igniter Assy 83620-60010

#1 Coil

90919-02077 (about 6.5" tall)

#2 Coil

90919-02083 (about 5.5" )

Thanks,
Paul

EMP is the correct initials, sorry for the typo. Thanks Danny for your input based on actual scenario training. My reading is somewhat mixed on the issue as well. Most sources still point to post '77 vehicles as being subject to the EMP effects due to the electronic distributors and the computers in modern vehicles. I think I will keep my original distributor in case the newer one craps out.

Thanks guys for your input on my question...Tin Foil hat back in the drawer for now.

@karp68

The coil is your

#2 Coil

90919-02083 (about 5.5" )

The igniter is difficult... very little label left... zoom it in... see if you can make it out.

 

[karp68]

Thanks Danny @Solace in Solitude ......I couldn't make out the number, but it is a different shape than the one I have. I keep reading the posts, by @FJ40Jim and I'm thinking I could use the igniter I have 89620-60070 (it lists as a 80 to 84 FJ40) with the NGK coil (It states....use without external resistor) listed above and not have to worry about an external ballast resistor or a Yaxaki wire.

If anyone has some input on this I would really like to hear it. It's a 1/1978 2F motor going into 1968 FJ40.

Thanks

I’m sure @FJ40Jim will validate you shortly.

This is the other igniter I have 89620-60010, it has the ballast resistor, and it says for years 1/75 to 3/76.....not sure if this is the better way to go??

 

[FJ40Jim]

Karp, the ignitor has to be compatible with the dissy. For a points dissy use the '75 ignitor. For an electronic dissy, use the aluminum case ignitor.

If you can use an electronic dissy and the FJ60 ignitor, then get a new 90919-02113 coil. It works with that ignitor and doesn't run a ballast resistor.

This may help answer some Questions
or
make more ?

Thanks so much for replying Jim, @FJ40Jim The dizzy is electronic. The aluminum case igniter I have, only shows for an FJ40....so I should look for a 60 series igniter to match up with the coil you listed 90919-02113

Part 89620-60070 (IGNITER ASSY) was found on the following models:

	Date range	Model	Frames/Options	Found in diagram
	08/1980-09/1984	TOYOTA LAND CRUISER	BJ42,FJ40	84-01: SWITCH & RELAY & COMPUTER
	Model Dates:	Matching Models:	Model Options:	Links to diagrams:
	08/1980-09/1981	FJ40L-KJA	USA, TP, 2F, 4F, RB, TPS	84-01
	08/1980-08/1983	FJ40LV-KCJA	USA, VAN, 2F, 4F, VKC, RB	84-01

Thanks again for the help!!

Hey Matt @RAGINGMATT , yes answers some questions and raises more........does this coil not use a igniter or is the diode (the black and chrome shield on the front) the igniter??

Thanks

I reread your post, Paul, and wondered if you are aware... 1978 used an 8ga Pink Yazaki resistor. It's a large pink wire, of a certain length (that provides the required resistance)... It's spliced into the large (8ga) BY wire, in the main harness. EDIT: both wires are 10ga... Not 8ga.

When I moved to DUI, I left the spliced Yazaki, but taped it off, since DUI requires unresisted (full battery) voltage.

I don't know how this plays into your plans... Are you planning to use a '78 harness?

Jim's final suggestion ,aye be your best approach, "If you can use an electronic dissy and the FJ60 ignitor, then get a new 90919-02113 coil. It works with that ignitor and doesn't run a ballast resistor.".

Just be sure your harness doesn't have a hidden resister wire...

 

[karp68]

Hey Danny,
I'm using the original '68 wire harness, I had no idea about the Yazaki wire until I read some earlier posts (including yours). I do like Jim's suggestion about the FJ60 igniter, so I'm on the look out now for one.

Thanks again,
Paul

 

[Coolerman]

FYI: The Yazaki resistor wire, and the BY ignition wires are 10ga, not 8 ga. Besides the battery/starter/ground cables, there are no wires in the USA spec FJ25/40/45 larger than 10ga.

this Coil CAN be used without a igniter


and for with one ....................?

i would reserve my answer for @FJ40Jim on the WITH A Igniter topic
