jensen 530 chipper feed roller issue.

[carlos]

the works tracked 530 has an intermitent problem with the feed rollers, it may work then after a while they will stop completly, on the circuit board the power light is on and the flywheel sensor light is on but the relay light is off or flickering, to get the job done i took the electrical connection off from the hydrulic solenoid valve and applied 12v direct from the battery, this worked fine ( apart from no antistress) the rollers works as normal

my thinking is that its the little rectagular shaped relay on the circuit board?

any one have experience of this problem?

is it possible to repair the circuit board?  

thanks carl

When mines started to play up like yours are. It turned out to be the solenoid valve on the rollers that was playing up.

i thought that the fact i put 12v directly into the solenoid valve and it worked fine meant the valve itself was ok but i could be wrong too.

It sounds as the solenoid is working but the relay is dicky, flickering isn't right. Most plugin relay problems (chipper or not) are with the connections, may be able to clean or just replace to be sure, and check contacts are tight.

It is also possible it's a wiring break or even the connection to the solenoid of course, but you have to change one thing and see how it goes to track down the fault.
