Engine Block Heater

[rmacdon5]

Hi,

I just purchased a used zetor 3320... not sure of the year.. 95/96 maybe? I was looking at the block heater and it looks like there are only two contacts on the 'heater element' coming out of the block but there seem to be three contacts on the power cord that plug into the element. Is there a third contact that has broken off (none that i could see) from the heater element? or does the chord just have one extra 'plug'?

Thanks

Only two out from Block seems right. i think you are missing a piece of cable usually there is a piece of cable Attached to the Block heater element that has a contact on the end wich is mounted at an easy Place to plug in these have 3 pin Connector, at leas the DEFA an CALIX heaters fitted here has.

The last pin is ground and leads to the ellements fixture.

After further inspection, it seems that a contact has broken off the element.

Any tips when swapping out the element? I have a loader so space will be limited.

thanks
