Warning lights-neutral, oil pressure

1998 Triumph Thunderbird: Neutral and Oil Pressure Lights on Console

Suddenly, these two warning lights stopped working on the TBird.

Fuses are fine. Bulbs are fine (to check I replaced both bulbs and fuses).

There was some water ingress into the connector housed in the headlight but I've used half a ton of connector/ switch cleaner on that and there's no visible corrosion.

I have yet to check that there is electricity at the connector in the headlamp-next job.

I think it unlikely that both oil pressure and neutral switches have both failed at once.

I will remove the tank to see if any connectors have come apart.

Battery is good and bike starts fine.

Anything else I should be looking for?

Check grounds. They may be common to both lights..

Yes, you are right, earth is common to both lights. Will do tomorrow, sleet and rain permitting...bike works okay without em though...

Grief, this is frustrating...no voltage at the console connector. Can I trace it back to the fuse box? No. Wiring looks simple but...

I've never worked on a T-bird, but I remember from the daytonas and S3's that I've had on my lift that Triumph used those generic 30A automotive-style relays instead of a sealed "junction-box" like most of the other mfg's favor.  There was no end of weirdness that can be caused by one of those relays with a dirty/corroded internal contact - and they are not sealed against the weather.

...but I'm not sure if the T-bird has that same type of harness/relays in it or not.  If it does, those relays cost about $8 or $10 apiece, they're available at most any auto-parts store, and are really easy to replace.  Good luck!

Thanks for the tip. Sadly, it's raining steadily here and I have to work on the bike outside. The good thing is, it still runs!
