a puff of smoke and now nothing 69 valiant electrical issue

I tested power up to the fusible link and it was fine.
So next check at the bulkhead connector.

Then go inside and do the same.
The fusible link bulkhead terminal has a seal so its not easy to back probe.
You can remove the connector and check the terminal OR go inside and backprobe there.
I recommend checking the inside first. That will be faster and removing the bulkhead connectors is a little bit difficult. You can come back to doing that after reading up on some of the tips to removing.

I am also wondering can you blow out individual gauges?
Easy!

Seriously when you see how the gages work and the board is laid out, its not that hard to see how one can get damaged and the others may not be effected.
