    Briggs diode wire harness part #844547

    Does anyone know the value of the diodes in the wire harness to the coils part number is 844547? What is the purpose of this diode harness? Will it prevent an engine from starting? Thanks for your help.

    The diode's prevent the modules from grounding themselves to each other. If the diode shorts open you can't shut it off. If the diode short closed it won't start, at least on one cylinder if one diode is bad.

    Don't know the values and not sure if any briggs dealer would, because most repair shops would just replace the harness between the igntion modules. would be more expensive for the shop to remove and replace single diodes.
