Can someone please tell me how this is supposed to be wired?? I thought I had it all figured out. When the right signal is on, everything is fine. When the left signal is on, everything goes crazy... All my gauges start going crazy and my flasher gets super hot and clicks... Ideas??

Do you have a trailer hitch? Check the front and back lights for rust and shorts. 2 cents Mike
 
one thing i did to mine this weekend is went through and cleaned all the grounds. ended up solving alot of my wiring woe's, specially since none of the electrical has been hooked up in probably 15 plus years.
 
The flasher wiring is pretty simple since you are not running the Hazard switch in your case.

First is this the OEM flasher?
Second tell us EXACTLY how you have this flasher wired.
Third are their ANY differences in how you wired the right side vs. the left?

No sir - no trailer hitch.

The ground for the relay is fine, but perhaps the tailight ground could be the problem. Are the tails on a 1970 self-grounding? I didn't notice a grounding wire on there...

The wiring part I am not sure if it is OEM or not. It is wires like this

And no, no differences in the sides. They worked just fine when I first got them working on Thursday night. But then driving it Sunday is when it happened.

Also, I noticed that my taillight on my bad side has now burned out... Grounding problem?

Thanks guys,
Jonny
 
Something changed if it was all working then quit. You need to figure that out. ;)

The rear tail light housings are grounded through the mounting bolts to the rear 'bumper'.

So the GW wire from the flasher is going to the B terminal on the turn signal switch?
Where does the 12V wire go? Fuse panel?

Is there a separate ground wire for the flasher or is the case just grounded?

Can you take pics of all this?

When the right turn is on and working properly, does the flasher get hot?

Something on the left side is pulling a lot of current to get the flasher hot. A fuse should have blown somewhere. What size fuse does the +12 go to?

Oh, BTW that is NOT an OEM flasher.

Coolerman,

I don't actually know if the flasher is wired correctly. I just guessed that was it.

There are 3 wires coming off the flasher. I knew one went to the GW wire, I knew one needed power, so I just figured the 3rd would go to ground.

I think it is just wired straight to 12v and not going through a fuse. That could be the first problem!

I am not sure what could have changed as I only drove it for maybe 30 minutes between fixing it, and when the problem started.

No, when the good side is working the flasher does not get hot.

I can take some pictures when I get home this evening.

Thanks again guys,
Jonny
 
The flasher is not grounded. There is one power wire and two flashing terminals on many flashers. Toyota only uses one of these. On many cars, the other flasher wire is used to light up the dash indicator lights. If it flashes really fast, there is a short, like would happen if you grounded one of the flasher wires.

If the left side "goes crazy and the flasher gets hot", chances are there is a short in this side circuit. The turn signals should be fused to avoid fires and other unpleasant stuff.

OK - so you are saying I should remove this ground? If that was the problem though, then why would the right side still work without problems?

Thanks,

Yes, remove the ground from the flasher. Tonight get a pic of the flasher part number. Maybe we can look it up to see what terminal should go where.

Please fuse every circuit you attach to the Cruiser. We don't want to read about your Cruiser burning to the ground on the side of the road....

OK man - sounds good.

What amp fuse should I run it to?

Thanks again,

Turn fuse 15-A,
You mights have this type of flasher like in the pic.
I am no expert,but
I think you have something wired wrong. It could be a side marker maybe a lic plate light grounded to the + wire going to the left signal bulb.
I think you need to rewire by following a wiring diagram for your rig, so you will need the flasher,turn signal switch ,tail lights,and haz switch all gone over and rewired if needed.
You can use this type of grounded flasher or a 2 connector flasher like in the eom. In other words your problem is not from the flasher, it is a wiring problem.
Do it right , or keep having problems, you are getting help form the wiring experts ,so follow what they tell you.

Unfortunately my flasher is nowhere near as cool as that one. Mine is old and in bad shape. Now is the black wire on this one for power or ground?

My only concern, is that if it is something wired wrong, then surely it wouldn't have worked properly to begin with? If it did work, and then stopped, surely that would indicate a loose/damaged wire/relay?

The wiring on this thing was a real hackjob. I have cleaned it up a lot, but apparently still have more work to do on it...

I will post a picture in about 2 hours when I get home.

Regards,
Jonny
