    Changing my boat gauges.

    Thank you so very much. Read thru instructions, think have one problem solved with voltmeter, think it may affect tach too. Will post more after test theory.

    Changing my boat gauges.

    All dodge, you asked who manufacturered the old gauges. Took a picture of old tach, and old voltmeter. Noticed some strange differences between old and new. Think problem is in new tach the way it is wired compared to old.

    Changing my boat gauges.

    New thought on ground jumper wire. Hooked it to new volt gauge, switched on all instrument lights came on, had 12.5 volts all gauges. Fuel gauge and temp. gauge was working not the tach? Moved jumper to fuel gauge 12.5 all instruments. Had a storm brewing did not get to test what was working.

    Traced down wire to horn. That means end on gauge should be on ign. I think?

    Changing my boat gauges.

    Ran a jumper from battery neg. to meter. Got 12.4 volts fuel, trim, temperature, & voltage. Tach 10.5, speedometer 10.5. Fuel and temp. gauges peg full right when power switched on.

    Yes, old gauges were working except trim. Fuel worked fine 1st year, started acting up close of season last year. Would read full or empty all the time. The old tach, temp, and volt worked great until started changing gauges.

    Changing my boat gauges.

    Have checked readings several times, definitely 2.6 on all but tach. Have tach set on 6cyl 3p. Going to hook up my timing light to make sure getting accurate reading.

    I got good readings today. Ign. on 2.6 volts fuel, trim, water temp, voltmeter, 6 volts tach. Running 9volts tach, 4 on rest. The engine starts right away, every time.

    Changing my boat gauges.

    Got my new multimeter today. Going out now to get readings. Did notice yesterday tach works as long as revs. about 900 or more. Does that mean got a short?

    Changing my boat gauges.

    I should probably mention trim gauge did not work when I purchased boat. Blower quit last year, however was able to hook it directly to battery. Now won't work at all. And fuel gauge been acting weird.

    Changing my boat gauges.

    The new gauges are crowline black sterling. The old gauge just says starcraft. Will try cleaning as you suggested. Did notice corrosion.
