Checking the oil pressure warning
indicator
1. Connect a penlight battery (1.5 V) to the
oil pressure warning indicator (LED).
Replace if it does not light.
CAUTION:
Only use a penlight battery (1.5 V) when
checking the LED. Other batteries (e.g.,
alkaline batteries or high-voltage batter-
ies) will damage the diode.
NOTE:
• The LED will not light if the penlight battery
voltage is less than 1.5 V.
• The LED only allows current to flow in one
direction. Therefore, if the LED does not
light, reverse the connection.
• If the oil pressure warning indicator is
installed to the outboard motor, start the
engine and ground the pink (P) lead to
check if the LED lights.
