Can you provide a little more info? Is it a Deep Ocean Engineering M5 system that you have? If so then you could try DOER in the US for servicing, their website is: http://www.doermarine.com/
thanks for your information, i already sent email to them, i wish they can help, cause i need wiring diagrams for brush system build by advance marine,
the main problem is, the guys who buy first time not get clean information about brush system.
Mike, i already sent email to them but not replay until now, do you have contact person for those company,
cause from web is not very clear information about contact person etc.
