Well, i just got the toronado dash in from my brother in law.
So far, its about what i expected. There is a caged power supply module
screwed on to the back of the gauge cluster. It appears to
be a switcher. It has a single large plastic power transistor driving
a transformer. There appears to be 4 DC outputs. each outputs appears
to be a 1/2 wave type DC supply. Three of the outputs have 33@100v
caps on them. I assume these are the power supplies for the display
tubes. The fourth has a 470 @10 volts. I assume this is for logic
in the display. From the cap values, i can assume 3 high voltage DC
supplies and 1 low voltage.

There are three wires (some doubled) on the input side. So, I assume
there is 12 volts, ground, and one switching wire. One would assume
the switch wire switches on 12 volts, but i am doing some further
checking before i put power on to it.

The unit has a soldered on fuse on the PC board. The fuse is fine.
Solder joints look OK. The semi's seem OK with fluke check in
circuit. Nothing looks burnt.

So that's what's there. We will see what we find after further sleuthing
and a bench power up. But from what i have seen, it looks fixable.

Bob
