Re: Radiator fan question, again Reply #25 – August 21, 2013, 06:16:23 pm Yahoo Message Number: 90764Why couldn't a rheostat be installed at the helm instead of an on-off switch? Couldn't this be wired to control the fan speed 100% and forget the constantly failing hydraulic fan control? Seems like this could be attached in #1 bay replacing the 7.5 amp fuse.aaamarine2005 Allure 430 Cat C-9 Quote Selected
