TR6 TR6 - Should turn signal work if hazard is gone?

Plagued with electrical gremlins all weekend... Can anyone out there say if the turn signal switch should still be operational with the hazard switch removed??

After swapping in a new turn signal switch I could not get any response from activating the turn signal. I just figured the vendor sent me a lemon, but (1) the old turn signal also no longer activated the blinkers (it formerly had b4 i removed it), and (2) the new one tested good on the multi-meter.

So for the heck of it I start activating the hazard switch off/on when the fuse mysteriously burns out. I now cannot activate the hazards at all because i keep going thru fuses. Screwed with that hazard so much that i ended up breaking off the red knob. The thing was ancient, so I'm just going to order a new hazard switch.

Not sure if the turn signal problem is related to the hazard switch problem; they both failed within 24 hrs of each other.

While awaiting a new hazard switch, I'd really like to get the turn signals going again. Just need to know if the hazard switch needs to be in place before I go troubleshooting the turn signal switch.

Many thanks in advance, hope you all are enjoying these final weeks of summer, saw a beautiful english white tr3 cruising Ocean Drive while i was in newport ri today.
 
According to the diagram I have, the turn signals go through the hazard switch on a 74 TR6. But you should be able to jumper the green wire to the light green/slate wire to get them working. The green is fused, switched power, and the LG/S is the power to the turn signal switch.

IMO, it's very likely that the switch failures ARE related; most likely by a short farther down the line. Because Triumph was so stingy with fuses, the fuses will pass more current than much of the wiring can handle easily.

Of course, I'm assuming you are aware of the Lucas vs American fuse rating difference ... if you've stuck a 35 amp American fuse in there, then it's a wonder the car hasn't caught fire.
 
...funny, i actually stuck a 35 amp fuse in there. when i turned on the hazards the thing glowed orange for about 2 seconds then went poof!

thanks for the jumper info Randall, i see a thicker solid green wire with bullet connector coming in thru the firewall. i'm pretty sure it was dead though (could be the problem); will test again tonite.
 
My suggestion would be to wire a test lamp into the circuit (either in place of the fuse or as the jumper across where the hazard switch should be); then remove all the turn signal bulbs and try to figure out where the short is.

If you want to use American fuses, then an AGC 20 is an adequate equivalent to the orignal Lucas 35. If that blows, then something is drawing too much current. (An AGC fuse is slightly larger physically, but can usually be forced into the clips.)

Many thanks, this was extremely useful in troubleshooting the turn signal/hazards issues. I isolated the problem to be the front left bulb which was completely rusted in its socket. Still having trouble getting all 4 to light at the same time with the same intensity.

I think the socket that had the rusted bulb base needs a better clean job. If i twist the new bulb a certain way it causes it to light correctly but then a rear one won't light at all. If i twist it yet another way it becomes extremely dim but the other 3 light properly AND hazards will be barely lit on all 4.

This problem is usually caused by a bad ground. I found a repair on the now hard to find Mid West club about adding a little bit of solder to each holder at the right spot. What a difference!!!. A couple of them took a second and third attempt,but I persevered.

I've got the article I think you are referring to, but AFAIK it was only for the rear bulb holders. Basil won't let me post it here, but if you drop me a PM with your email addy, I'll email it to anyone.

I started with the same repair Nelson wrote about (except that mine were so bad I had to add a length of wire to bridge the gap); but then discovered that new rear 2-filament bulb holders are made differently and don't have the problem. Instead they take a ground wire directly to the bulb holder (instead of to the lamp assembly) which seems far more secure to me.

Randall, that is indeed the one I was referring too. It was a bad case of brain fade at the time I wrote it and I couldn't recollect Nelson or or the club at that time period.

One of the DPO cut all wires to the Hazzard switch on my 71-
tr6 and all lights and turn signals work, but I dont know if they taped wires together
