DOC here,

NOW is a good time to learn how to use it..

WHY it flashed is of no importance..the FACT that it are testing in DANGEROUS waters..

not sure what you mean does it matter whether it's 6v or 12v as far as 50 sticks of dynamite senario?
1, 6 or 12 volts..with you "probing " around with power..into a connected sender line you are heading for one hell of an explosion and fire..

You are sending 12 volts (or whatever voltage you have) Through a sender (that should be on ground) INTO and through 30 GALLONS of gasoline and inside of a grounded tank..IF you didn't read and fully understand my last need to read up on fuel senders and systems, and learn to use the meter OR find a good shop to repair the system to be safe..your headed for BIG trouble.
