I"m seeing 15 buss switched positive to tach and voltage stabilizer
but it doesn't look like the voltage stabilizer controls positive to
the tach.

P 97.43 in Bentley shows a ground from 10 ("behind dash") to 14/5 of
the big white connector to the cluster. Inside the cluster, in part,
this ground connects to voltage stabilizer, hi beam indicator light
and, the coolant gauge. Most likely to the blinking light portion.

There is a ground path on the blue ribbon that's prone to failing.

Ground to the voltage stabilizer is provided via the mounting tab, or,
a leg on the stabilizer.
