2004 SD217 electrical problems (stumped!)

Hello Everyone,

Below is the email that I sent my boat mechanic about electrical problems with my 2004 SD217o/b. 

After the guys jumped the batteries to start the boat I noticed
that I didn't have any helm instrumentation once outside your
breakwall including the marine radio but I was able to make it to my
marina without any engine problems.

Once docked I wasn't able to restart the boat.  After checking
the breakers and thinking that the under-charged

batteries might be the problem, I filled both batteries with
distilled water and charged them.  I was still unable to get full
instrumentation at the helm nor any power to lower the motor.

Checking the voltage at the battery, one maintained only an 80%
charge while the other only a 60% charge.  I decided to replace
the batteries with two new AGM batteries.  Here's what I can tell
you:


Cleaned the cables, battery leads and installed them:

After turning the key to the acc. position there was no voltage
registering on the helm gauge.

The gas gauge would instantly pin to the right past full.

Systems that worked included the horn, nav lights, courtesy lights
and the music radio would also power up.

The depth gauge worked intermittently.

The marine radio did not work.

The bilge pump would not run.

The motor would not lower into the water or even try.

The accessory plug registered no voltage with a multi meter.


I check the breakers again which seem to be fine.  Cleaned
corrosion from the fuel sender ground wire and reattached it with
no effect (may attach ground wire to a different location and
check again).

The boat hasn't run since bringing it over.  Any suggestions?

If anyone was any suggestions it would be greatly appreciated.

Thanks,
Paul

    I forgot to mention:  Attempts were made with battery1 in isolation then battery2 then with batteries 1&2 together.  Exact same result all three times.

    Did you check the relays back by the batteries?  Mine are mounted to the transom.  Also, did you hook up a voltage meter to the panel at the helm on the different switches?  You ignition switch will have a constant 12v hot - I would check that on a multimeter to see if it's getting power.  Really sounds like a relay or possibly some melted wires going from the battery to the helm.
