Subaru Repair: Speedometer and tachometer problem on 2004 Forester, 12v batteries, warning lights

Question
Speedometer and tachometer don't read.  Everything else works fine.  All fuses check out- voltmeter reads >13V on both ends of all fuses.  Background- found battery dead yesterday; put on one of those carry around 12V batteries and jump started engine.  I drove it and it ran fine, but reads zero on both tach and speedometer.  No warning lights illuminated either.

Thank you,
Fred

Answer
with out checking the car for myself I couldn't tell you much.  I would guess a fuseable link or a shorted wire somewhere in the system.  This one may be a tricky and expensive fix.  It could also be your instrument panel.  Sorry I can't be more help.
