I have a 99 Larson with the Volvo 4.3 L 190 HP engine. When it starts
it runs quite well but today it seemed to be totally electrically
dead: no noise at all when trying to crank, no lights, no horn, no
blower, etc.

The battery is brand new (one day old), fully charged and the clamps
are tight. This has been an intermittent problem where I would let it
sit for a bit then it would be ok but today it would not show any sign
of electrical life at all. The positive cable seems to be tightly
connected down near the starter. I can't get at the neg. cable. The
fuses seem to be ok and if it was a fuse I would think that just some
circuit(s) would be affected and it would not be this intermittent
problem.

What should I be looking for that would shut down the entire elec.
system?

Please help! I am very far from any Volvo service shop and need to
fix this on my own. I am sure this must be something very simple I
do have an ohm-meter but it was at home three hours away today.

Any ideas would be much appreciated!


While the fuses are probably not appearing blown, check them with a
continuity tester anyway. All of them. Then check the rubber covered
fuse holders & the fuses themselves for dirt/grime/film and clean them.
On the SX drives, I think there is a pair of fuses, like 20A & 30A,
that power most of the circuits including the solenoid(except for the
starter).

This is from memory, check your manual.

Let us know how it goes.
