Appreciate the reply. Thanks.
I had removed the batteries and checked on an electronic load – Even applying a 1A load one battery Voltage collapsed to <1V and could not even deliver an amp. It measures 8V open circuit. The second battery measured 11V but again any load would just drop the voltage <3V. The batteries are about 5 years old and original supplied.
(The electronic load is a test equipment I use with normal work job). Also both batteries showed bulging signs.
I have replaced them with new Yuasa NP7-12FR 12V 7Ah
If I manually move the chair off the charging contacts (rotary manual accessory handle) I get fault code 2 which stacks up with the manual saying no charge voltage so returning to charge contacts manually then shows the code 11. (Encouraged that there is still intelligence working in system.
There is no movement of the chair motor with with the normal handle switch or remote control.
Lift is about 5 years old but barely used to be honest. My parents purchased it new after my father took ill but thankfully recovered. Its not seen much use at all.
I’ll take a look at the PCB relay, thanks for the tip, When you say the brake function is that part of the relay check or another component?
PCB looks like a right pain to get to. Is there any procedure advised. Do you leave the chair attached to rail?
