Hello The Net,

Is this a very old T'Bolt or the newer e T'Bolt ?
I like the single power supply even though it is 24VDC

It's the original Thunderbolt. It's the same as the gold-cased OEM units
available on the bay, but it includes an internal dc-dc converter that
provides the 3 voltages for the gps board.

Hello The Net:
So far I have experienced 2 different versions of the T'Bolt firmware.

Using Lady Heather to compare, both versions perform similarly, when

Hello The Net:
My T'Bolt died and it was not the external power supply.
Any pointers to troubleshooting techniques and a schematic ?
I should first start ohming out the on board DC power distribution,
then trace the various voltages, after DC power is applied.
I am only finding one test point,
