just wondering if someone can tell me what the attached photo is? It was connected to 2 wiring looms in my 2001 Evernew e-series?. stamped on the unit is 1C30. Any help would greatly be appreciated
regards
Michael

Looks like a heat sink to me, probably a voltage regulator of some sort. Hopefully someone more confident in their knowledge of such things than I can confirm.

Hi,
Thanks for your reply, appreciated

If you have a multimeter, measure the resistance between each pair of screw terminals, and between each of the terminals and the body of the heatsink.

Following Cuppa's suggestion I Googled "Voltage Regulator 1C30" and got several results worthconsidering. Cheers

Can you unscrew it and show us the other side? Or is it glued down?

Just took a picture of the back of the unit and a couple of other pics. The unit was connected to a wiring loom (red wire only) that hooks up to the battery. The second red wire hooked up to another wiring loom that looks like is feeding up from under the van. Ill

Thanks for the follow up Dorian, wonder why it would be used in a caravan then? Btw, looking at the (what I think is dodgy wiring) why would the main wiring loom be split to attach to the battery?

My guess it is a diode between the van battery and the 12v 3 way fridge feed from the tow vehicle. Coromal used such a device to prevent the caravan battery from discharging back through the fridge. However I found that that the voltage drop across the diode in our coromal prevented the van battery from effectively charging and destroyed 2 batteries in 4 years before I discovered what the cause was.

I magnified the image and it looks like it is a circuit breaker.

As already explained by Alan, the diode must be preventing backfeed into the car battery.
A typical Jeep alternator would probably generate between 100A to 120A. This means that each diode would have an average forward current rating of 33A to 40A. One good thing about this arrangement is that, if the in-use diode fails, you can simply move the terminal to one of the two spare diodes.
The heatsink would be the common anode terminal for all three diodes, whereas the studs would be the individual cathodes.

Just trying to work out how to post the pictures

Just worked it out..

The device must consist of three diodes, only one of which is being used in this application.
Something similar ...

Draw too much current and it shuts down
As already explained by Alan, the diode must be preventing backfeed into the car battery.

thanks for looking at this
I am truely great full for all of your replies. Have a good day
