Valvoline VR1 on Woot

Are you a Woot member? $19.99 for a case of 6 quarts with free shipping for Prime members. As with a lot of stuff on Woot, It might be gone any minute....

YMMV, but on my 70 TR6, the ground to the hazard relay originates at the Cabin Ground Point under the heater hoses next to the battery. From the hazard...

[RatRidgeRoadster]

I think you need to go back and double-check that you have power on the purple/red wires at the relay. I guess you could have some very high resistance...

[RatRidgeRoadster]

Are you still reading 70/80 something Ω across the coil with the power removed? If so, why don't you connect the relay coil (W1 & W2) directly to...

[RatRidgeRoadster]

The starter relay and hazard relay are basically the same, maybe a slight variation in the terminals. If it turns out you need a relay and don't mind...

[RatRidgeRoadster]

The other wires are the front and rear signal lights. When the hazard switch interrupts the power from the turn signal flasher to the turn signal switch...

[RatRidgeRoadster]

Were you checking with the Hot purple/red wire connected? You should never check resistance on a powered circuit.

Guess I should have mentioned...

[RatRidgeRoadster]

The meter shouldn't be jumping around if you're holding steady pressure on the leads. I'm reading 74.4Ω on mine, so you're in the ballpark of where it...

[RatRidgeRoadster]

If there is still power on the purple/red wires at all times and it doesn't click then either the black wires are not a good ground or the relay is kaput...

[RatRidgeRoadster]

That would pretty much indicate that the hazard half of the hazard switch has been bypassed.

Just curious, and this may not lead to fixing...

[RatRidgeRoadster]

My picture is with the steering wheel and hub removed.

TRF seems to agree you need the 3.4" one.

Can you hear a click from...

[RatRidgeRoadster]

I'm a little late to the party, but I just came upon this diagram I made for someone else if you still want to use the 74 switch.

...

[RatRidgeRoadster]

Yes. Pull off the rubber surround pad and you'll have better access to pull out the horn button. Should be able to pull it with just your fingernails....

[RatRidgeRoadster]

Have you checked the horn button and brush? It sounds like everything else is good. After you pull out the horn button and spring-loaded brush, insert...

[RatRidgeRoadster]

Pretty sure the 70 model was the only car to have the breather (flame trap). If your valve cover has a hump where the hose is connected and not flat like...

[RatRidgeRoadster]

I would think with just a few exceptions the grounds are the same as depicted in that excellent TR6 ground point pictorial. I think you previously...

[RatRidgeRoadster]

You can easily bypass the ballast resistor wire by moving the white/yellow wire from the starter relay to the fusebox terminal where the white wire(s)...

[RatRidgeRoadster]

If you have no click, the problem will be the starter switch, the starter relay, or a defective seatbelt module.

With the gearbox in neutral,...
