wilson switch?

[killerv]

Hi there can anybody give an electrically challenged guy instructions on how to installl the famous "wilson switch" on a 1990 LJ78? It has the 2l-te engine and has a real problem starting cold. I checked the voltage to the bus bar and it reads 12 volts fo about a millisecond and then drops to zero so I think my timer is sc**ed!

Simply unplug the temperature sensor for the timer at the thermostat and it's bypassed. The ignition key is your 'wilson switch'
If bypassing the timer doesn't energize the glow circuit then it's likely the relay at fault.

next question were is the temperature sensor found and does this lead to premature wear on the glow plugs?

track down the relay that goes to the plugs from the battery. You need to get past the timer, so basically if I remember correctly, and this was on an '82 bj42 so its probably diferent, I went batteries--> relay/my switch--> then plugs The switch powered the relay. Make sure you get a switch thats voltage sensitive for dc (in my case it was 24v).

Most likely either the timers pooched, or the resistor is not resisting enough.

has anyone else done this on an LJ-78, it will likely be the big question for this fall, anyone have a step by step on how to do it with pics should post it up

YES PLEASE!!.....
Anyone??

i have the same problem as well new glowplugs made no differnce

too easy:
wire from battery to wilson switch
wire from wilson to glow
done.

or

wire from battery to wilson switch
wire from wilson to relay
relay to glow bus bar
done.

hold for 5-10 seconds
start
if it doesn't start right away then glow again.
if it does start but runs rough then hold the glow while it is running till running smooth.

no warranty with this info.

hi Wayne and thanks

 

[RHD Toyota's]

ahh where do you get a wilson switch and does anyone have any pictures of what to where? Catch my drift I know nothing, help!

It's the sensor on the thermostat housing with the two wire plug. The single wire sensor is for the temp gauge on the dash.

Does what lead to "premature wear on the glow plugs" ?

thanks my man , glad to know im not the only one that knows nothing, and thanks for asking the questions that i feel stupid asking.

wilson switch = push button starter switch available at any parts store

no problem Champjack,

And thanks again Wayne

Which would be better and where would you splice into, keep in mind I have little idea as to where most of these parts are but with some instruction, it'd be no sweat.

all i did was take the yellow sensor wire and cut it half extend and reconnect to the momentary switch on the side of my dash.

works great.

I'm selling a bunch of these beautiful switches, that feature a dust boot to keep debris out of the switch and an engine start tag with lock washer.

These are a few pictures of the button itself
15 CDN is what I'm selling them for, plus shipping, PM me, I may do deals if you want quantity...

The switch has some brass connectors that use a special plug that I don't supply, I just soldered them on and shrink wraped, it is a nice strong connection.


thanks for your interest
Eric

 

[Gold Boy]

that's a petty fancy switch Eric.
even my 74 does not have a light dimmer...

 

[Eric Winkworth]

hahaha it doesn't? well my pimp 70CDN spec came with dimmer, suspension seats and wieght reduction via rust that has fallen off in the last 20 some odd years
