20 Most Recent 1977 Triumph Stag Questions & Answers

Your half way there. All you need is a wiring diagram to trace the wire from the ignition to that fuse. Most likely it is one wire from the ignition, then it splices to the different fuses. In my experience the splice fails(corrosion), Some times you loose one area, some times all. Depends on which side of the splice is corroded the most. Splices are hard to find. Even harness diagrams can be as much as 2 feet off. I usually find the color code of the wire and run a new wire. In your case, it would be from the ignition switch to the fuse panel.

To replace the battery in your Triumph wristwatch, you may need to use a specialized tool to release the steel hold-down. Here are the steps you can follow:

Remove the back of the watch using the tool you have.

Locate the battery and the steel hold-down. The hold-down is usually a metal plate that covers the battery and keeps it in place.

Use a flat screwdriver or a specialized battery removal tool to gently pry the hold-down up and release it from the battery. Some hold-downs are held in place with screws, so you may need to remove screws first.

Once the hold-down is removed, gently lift the battery out of its compartment.

Replace the old battery with a new one of the same size and type.

Replace the hold-down over the new battery and press it into place.

Replace the back of the watch, making sure to tighten the screws securely.

Note: If you're not comfortable with replacing the battery yourself, it is best to take your watch to a professional watch repair service for assistance. Replacing the battery improperly can cause damage to the watch.

The three fundamentals... 1. fuel 2. spark 3. compression Low/zero compression would explain faster than normal starter spin, but questionable root problem with "just cut out". Are plugs wet with fuel? If not, verify carb bowl has fuel at proper level. If plugs are dry, pour a couple tablespoons of fuel down the carburetor and see if it fires. If it fires... its carburetor or no vacuum/compression. If it doesnt fire with raw fuel, then likely no spark, followed by low/no compression. Recheck spark with a cheap spark tester, the kind with adjustable gap, and verify check actual spark. Do a compression test.
