ynot 45 Posted January 17, 2019 Share Posted January 17, 2019 Hi Trying to work out what is considered to be to heavy drag on B&G autopilot hydraulic ram. Does anyone have a contact for checking this? Or tips Thinking solenoid might be dodgy however it does engage and disengage. Compared to a similar setup on boat next door it is a sh*t load heavier to move. Cheers Quote Link to post Share on other sites
Island Time 1,235 Posted January 17, 2019 Share Posted January 17, 2019 Sounds like the solenoid is not opening correctly, or wrong fluid. Do you hear a solid click when engaging? Noise should be short and sharp. How old is the unit? What oil is in it? If you weren't aware, I'm a B&G certified tech... Quote Link to post Share on other sites
ynot 45 Posted January 17, 2019 Author Share Posted January 17, 2019 Hi IT Will check for click later today. Using hydraulic 10 Thanks will let ya know arvo Quote Link to post Share on other sites
ynot 45 Posted January 18, 2019 Author Share Posted January 18, 2019 Click click it goes The engage click is slightly louder than disengage. Should the unit be magnetic when engaged. Or. Maybe the valve inside is not actually moving completely Quote Link to post Share on other sites
Island Time 1,235 Posted January 18, 2019 Share Posted January 18, 2019 What is the Amp draw on clutch engage (magnetic coil?) Excess resistance can be mechanical in the steering (take the ram off, check for steering resistance), or the ap drive. Fluid restrictions (damaged, kinked or de-laminating hoses), blocked or sticking valve block, magnetic coil not providing sufficient power to operate the valve properly etc. This is not an electrical motor issue. If the helm has normal resistance with the ram off, the issue is the connection, or the hydraulics. They would have to be removed and inspected.... Quote Link to post Share on other sites
ynot 45 Posted January 18, 2019 Author Share Posted January 18, 2019 Yup ram off its free as a bird. Rest is all good. Will remove ram and take to hydraulic fixer to check. Not sure of relay amp draw as yet but guessing not that because it's in a non energised state when not in use so must deduct from that the valve is sticky maybe... Assuming the solenoid only works one way and spring internally returns valve to bypass. Quote Link to post Share on other sites
Island Time 1,235 Posted January 18, 2019 Share Posted January 18, 2019 Yup, or a broken spring.... Any hydraulics place should be able to sort it then... Quote Link to post Share on other sites
