    Question Motor starter is bleeding? Blue goo

    I have two 1993 Maxims that have GE Starters that are emiting a strange blue goo. It is in only two spots, and is not coming from any out side source, IE coolant residue from AC unit. The top of the starters are clean but this goo is dripping out of the bottom? I cut an Spark Killer in half and its not coming from there.See atached pictures. Any ideas? Thanks!

    Check to see if the coil are is abnormally hot after operating for a while.
    If an AC contactor armature does not pull in all the way, coil overheating can occur.
    The coils are sometimes dipped in a tar like varnish during manufacture.

    I took the starter apart thinking the same thing as you mentioned, and the coil is as new.
    No signs of over heating and the coils coating is orange not blue?

    Default Just guessing....

    here spitballing but it sure looks like either some of those blackish wires are suffering from heat and the insulation is melting or the black housing of the relay there is melting and the resultant goo appears to be blue instead of black. Probably the former but without a closer inspection it is too hard to say which. Either way I would not run it until I figured out what the hell is causing it. generally speaking melting goo type substances inside electronics enclosures is frowned upon LOL.... Good luck finding the source. Peace

    Could it be corrosion from the wires or other electrical parts mixed with oil or other liquid?

    Default goo

    Might someone have used an "anti-oxidant" paste on the wires? If these were thought to be aluminum wires, it would be standard practice and does ooze when heat or time has been applied.

    After looking at everything, it seems the only thing that makes at least a little sense, is that oil wicked thru the multi conductor cable. There is a cloth thread and a yellow and green ground wire. The box the wire ends in is full of oil, there is no sign of heat in any of the wires or contactors? Thanks!

    I have seen problems on VW and Audi cars. When coolant or oil pressure sensors using sealed connectors fail. The fluid is forced through the wiring system.

    The oil filled box was on a blower. There was a ground wire {yellow and green} inthe multi conductor cable.
    Solved!
