Waeco CF50 Combo Plug Getting Hot??

Moggs

You might check the fit of the plug in the socket. I find the merit plugs need the side connections prising back occasionally so you get a really tight fit. I have actually hard wired the Waeco lead back to the second battery so I don't use a plug. On corrugated roads the plugs can still be a problem.

Got the drawers yet? Dropped over to see Aaron this morning about servicing.

As stated above the fridge works more efficiently when running on it's own wiring system with the relevant fuse to avoid the plug heating (and probable failure) you are having now.
Electric motors run more efficient with-out variations in their power supply caused by overheating, voltage loss and variable voltage caused by other items connected to the same circuit.

It is quite normal...you need to appreciate that a lot of amps are passing through the plug ALL the time with no way of cooling down. I've pulled the plug out and got a bit of a surprise when I touched the positive tip. If you wiring was doggy then you'd blow fuses, etc.

Had my rear power setup for 5 years which consist of the normal Toyota plug, re-wired to the 2nd battery and a Narva plug. Have had no ill effects to the Waeco CF50 or anything else.

Anaconda have the leads at a reasonable price I think. We hardly ever use ours out of the car now though. Like how the drawers fit staright in? Will get the same set for the next car.

We're off to Tassie in January with the son and son in law (both with discos) so I thought I'd get Aaron to check the Patriol before then.

Moggs,

How hot are we talking?

The merit plug & socket are rated well above the amperage your fridge would be pulling.

My guess is a poor, or dry joint. Check for a good contact between the copper conductors and the plug connectors. Maybe some insulation is in the way.

High resistance joints equals heat and poor performance.

Thanks for all the advice.

I found the problem. Pulled the plug apart completely and there was a small short where the positive wire passed over the negative metal prongs inside the plug. The heat shrink that Waeco had put over the connector had worn through. I would have thought it would blow the 10amp fuse - but must have only being small enough to create some heat. All fixed now.

If your plug is hot then maybe check that the same issue hasn't occurred.

G'day Moggs,
I have a cf 50 as well and have had problems with this cheap plug.
I replaced it with a Hella 8 Amp plug and used Put Hella part No. 4123-00 female sockets off the battery and the side of the 240v power supplies dc output.
Works a treat will not rattle around and get hot as they are a solid fitting connection.
The fridge pulls the least amount of power than any fridge I have seen, Just a shame they used a $2 plug instead of a $7 one.
My fridge is still going strong after 4 years and will definately buy another Waeco!

The plug warms up because the connection is not good enough. I cut my Waeco cable and put an Anderson Plug in. I the wired and Anderson Plug in the car. When the fridge is in the car it is plugged in via Anderson. If I want to use it elsewhere I just plug the short section back on and the original plug is there.

Cheers.

Moggs,
I have a CF40ac which doesn't get a hot lead but when you select the turbo function it will then flash the error light after about 2 minutes. I checked the voltage under load through the standard lead and it loses about 1.1 volts through it. I then made up a lead out of 6mm cable and plugged it into the fridge and socket and tested it under load. Voltage loss was 0.05volt and I did not get the error light flashing at all. I ran it on 7 led's and turbo for until it reached the desired temp and was very suprised because rather than -18degrees it actually went to minus 24.5 degrees with ambient temp @ 28 degrees. I really think the lead that Waeco supply is not up to standard and heats up because it cannot draw enough amps like jumper leads heating up when jump starting a car. I also spoke to a Waeco reseller in Melbourne who has a CF40 and CF80 and he uses the lead from his cf80 on the cf40 as well. It seems as though the cf80/cf110 lead is a heavier duty one. The only visible difference between the two is that the cf25/35/40/50/60 lead has a right angle connection and the cf80/110 has a straight connection.
