ok , Firstly , thanks to everyones imput on this melting plug issue.
Went to a auto elec yesterday and fitted a new hella plug , upgraded the earth to 8 mm cable , ensured a very good earth , tightened pins in the female plug ( that was replaced the day before) and ran the fridge for 2 min during a amp draw
test. The fridge was drawing 8 to 9 amps . We touched the possitive end of the plug and it was still very hot.
We then desided to replace the fuse with a 20 amp fuse to see if the heat was caused by the 8 amp fuse trying to carry 9 amps . Still got hot.
The auto elec then advised that he didnt think the hella plug was really capable of pulling 9 amps and advised anderson plugs were the go.
We then replaced the plugs to anderson plugs and made up a adaptor from hella plugs to anderson , so I can use it with my ac adaptor.
I asked, why does the plug come with the transformer and not my battery , he seamed to thing it was the type of power that came out of the transformer that made it more compatible .
Anyway , ran the fridge and touched the terminals , no heat at all . Not even warm. I also notices that my fridge went from 30 deg to 0 in less than 10 min. i
I have it plugged in for 2 hrs now and will
check for heat shortly .
once again , thanks for everyones help.

Good to hear you got it sorted RC. In the end 90% of fridge issues seem to come down to poor plugs & thin wiring. The fridge pulling 9 amps appears a bit high but it may have been the heat generated in the plug causing that. Would be interesting to know if the amps have dropped now as
well or if that is normal for the big Waeco.
Cheers Craig......

There you go!
I knew an auto sparky could fix it for you!
The curent draw should be the same on the tranny... not sure about his theory on that one!

he said something about the transformes pushes more power that what my fridge needs , as the fridge was pulling more power than it could get in the car . ????? or does that sound like gobble de gook ???.
After all this , I still think the contact between the fuse and possitive pole could have caused the issue .
anyway all done now .

ditto
if you try to pull too much power from the trany it collapses and wont give anything...else it can only give what it was designed to putout providing demand meets that output...if demand is lower then thats all it will give...if its higher it collapses and you get nothing

Chaps,
I think you will found the Mobitronics power supply for the 80 and 110 litre Waeco's is 24Volt DC.
That would mean if your fridge draws 9 Amps at 12Volts it will only draw 4.5 Amps at 24Volts on the Mobitronics supply. Halve the current and you'll only generate a quarter of the heat.

What size Waeco are you using?
I have a 60litre Waeco and have had no real issues with it. I actually cut the ends off the 12 volt cord some time ago and replaced it with an anderson plug simply so I kept the connection secure.
The Waeco has been fine but when we are travelling the fridge does not leave the back of the Disco and on the last trip I found that it is just too deep and things in the bottom get lost never to be seen again until clean out time.
Recently got myself the same size engel. It is much easier to see and find things in the fridge.
I have now found myself trying to explain the wife why I need to keep both of them....."I just do" does not seem to be a satisfactory answer.....lol

- hmmm, that suggestion sounds familiar :-)
