I found the problem. The front reservoir float had separated from the
contact rod thus closing the circuit and causing the light to come on.
I can disconnect the front reservoir plug and the light stays out. THe
back plug is still connected and works to monitor the fluid level. This
is just a short term solution until I can figure out if I can repair the float
indicator or whether I'll have to buy a new reservoir. Does anyone know
if there's a kit to fix this? BTW, Thanks to all for the assist.
