Triumph Repair: Hazard switch, fuse panel, hazard flasher

Question
QUESTION: I've been having problems with getting power to the wipers, brake lights, reverse lights and turn signals. Now according to the electrical diagram the hazard switch is essentially a junction for all of these. What I don't understand is, how do they get power? The only wire that feeds power to the whole switch is coming from the hazard flasher unit. If I take that power wire and connect it directly into the wire that feeds the wipers, the wipers only work intermittently with the hazard flasher unit. How on earth did any of these things get non-stop power in the first place?

Also, I want to add that I tried replacing the switch several times. Took them apart cleaned them and everything. Nothing changes. The hazards themselves work though.

Thanks in advance.

ANSWER: Michael, I need to know what year and model car this is.

Answer
Hi Michael,

My diagram don't show that at all. I see that several items you mention are powered by a purple wire from the fuse panel and others you mentions are powered by a green wire from the fuse panel.

I learned a long time ago that when you had several items that don't operate you need to pick ONLY ONE circuit for one item and trace that one item from load (item that don't operate) to it's source (battery) and most of the time that will correct the other items.

However, in your case of the wipers being powered by the out put of a flasher unit means you have some wires plugged into the wrong place possibly.

It still does not matter, just pick ONE and ONLY ONE item that don't work and follow the diagram from load to source with a test light and you can not fail to find the problem. Forget systems as they are usually useless. Testing is the ONLY way to correct it. Always pick a simple circuit of the items that don't work. Wipers have more then one power source so that is a bad one to use.

Brake lights and reverse lights are both very simple circuits so use ONE of them.
