Warning Light
The Water/Methanol Failsafe can also be used to directly activate a warning light (Autometer PN 3239 or similar).
Connect the warning light black wire to ground and power the light with the high side output – see Figure 5. Alternatively,
the low side output can also be used to turn the light on if the white wire is connected to +12V – see Figure 6.
WATER/METHANOL FAILSAFE GAUGE
The Water/Methanol Failsafe gauge comes with the black bezel installed however, a silver bezel is also included. To
change the bezel, orient the gauge so you are looking at the faceplate. Rotate the bezel counter-clockwise to unscrew it
from the gauge cup. The bezel, lens, and rubber spacer are all removable. Reassemble the gauge as shown below in
Figure 7. Note: When reassembling the gauge, it may be necessary to apply a light amount of pressure on the lens and
spacer to keep the faceplate from rotating when reinstalling the bezel. Do not over tighten the bezel when
reassembling the gauge.
