REFLECTOR: fuel sight gauge

[Alex Balic]

Grigore-

The LED's are polarized- they should light up with 3v, but you should have a
resister in the circuit to run them continuously, and for sure to drop the
12v down to the 3-5 that should drive them - try something low like 100
ohms- they don't need to be large ones wattage wise I am thinking my units
came with some instructions- you might ask Vance for them.

Does anybody know how to electrically install the Atkinson sight fuel
gauges?  In other words, can one just connect the little LED to 12V?  I
tried to connect it to 1.5V, then 3V and did not lit; I'm a bit affraid to
expose it directly to 12V.  If resistors are supposed to be serialized with
the LED, does anybody know what resistors and where this info can be found?

 

Thank you,

Grigore
