If I made a mistake and put the fuse on the wrong wire will it still worK?

Most often there is only a (+) going to things so there is no choice as to which wire to put the fuse on.

For my own piece of mind I will check it again when I have some spare time.
But I cliped one lead of my Ohm Meter to the Black Wire with Red Dots Socket on the Connector a when I touched the probe to the Valve cover that is the one that had continuity.

Do they make 1 amp 2 prong blade type fuses? I have never noticed.

I just got back from re-checking the wires again and I put the fuse on the wrong (-) color Brown Ground wire.
I indeed could only get (+) voltage frorm the Black Red Dotted wire
Thanks for correcting me on this.

Thanks.
I was wrong the Brown wire as you said is the ground wire.

It is a coolant heater independant of the car's engine. Mo knows all about mine as he installed it! Come to think of it I also got my aux pump from him!

Mo, I like the new pic of your wagon! I'll have to take a pic of mine in the snow one of these days.


In my observations the aux pump would run both directions. If you ground the brown wire it circulates one way. If you ground the black wire it runs the other way. If you plug it into the existing connector you don't have to worry about it as it has a tab that only allows it to be plugged the correct way. But since I bypassed mine I experimented with it.

How's that webasto working?

Diesel911- glad you got it sorted out BEFORE you had any issues. I am going to make it a best practice to do that mod on any mercedes I see. and yes, they do make a 1 amp blade fuse. I am using 2's, because that is what I had on hand. but I will be getting some ones next time I think of it.

Since I have been running the aux pump in combo with it much better. It cycles on and off for awhile now rather than just cycling once for a few minutes. I am wiring it to a remote starter/door lock remote so that I can control it remotely. I have most of it installed but have not had any time lately. I also just put in a new battery this past weekend as the old one was not holding a charge so I couldn't run the Webasto as it would kill the battery and I would not be able to start it, now I can run it and there is plenty of juice left over to start the engine. I still mostly plug it in as it is simpler (until I get the remote option done). I need to add one check valve where the coolant line coming into the engine bay from the Webasto tees in the line as it generally flows the other way. Should be golden after I do those two things! The only other thing I can see is possibly one more pump on the main Webasto line to aid in circulation as the stock location helps but with all the loops I'm sure another would also help.

Actually I have not done the swap yet.
The 1st time I did the job I was in a hurry and I was in the dark with my Wife holding a Flashlight.
I would like to improve my chances this time and work in the daylight when the car is available the next time.
Also I need to find some blade type 1 amp fuses as I have none.
If I cannot easily find any I wll have to change the Fuse Holder to a Bus type fuse.

The buss type fuses in AGC are going to be the easiest to find and the ones at the lowest price! I'm glad you got that color code thing figured out! Here's what I've known to be true of basic primary circuits: Brown=ground
Black= line or feed
Red=directy powered accessories from the battery, also known as always hot.
Green=Ignition power. This is typical of gasoline engines, but diesel engines usually use this code too in say for instance, glow plugs, considered an ignition source.

Other colors imposed on the primary color are subcircuits and will vary by accessory.
Red dots on the black wire for instance mean that this is a feed line, but the decision to switch the current on and off is made by electronic brains in another location, like your comfort control.

in FLA the pump seems redundant, I unplugged mine right after reading about the fire in the other thread.

I ended up using forum member AMH's advice and get the parts from Napa.

The Napa # 7823101 water proof fuse holder is kind of bulky, it cost 5 bucks. There might be a better solution out there.


The 1 amp AGC fuse is less then a $1.

boating supply stores have waterproof fuse holders as well. but $5 sounds about right for any of them

Hey DeliveryValve, did you quit selling your little "kit" for this? I bought one and thought it was a pretty good value for $25...

Question: if connected to brown wire, it runs one direction? and if on black wire it runs another way? does that mean the function to the pump will be different from original function if not connect to black wire? Thanks in advance!
