Anyone build there own fuel pump bypass cable?
 
Has anyone built a fuel pump controller bypass cable? I might be able to get an old controller and use the connector off of it. If I can't get a old one anyone know which bmw p/n is the correct one to connect on the fuel pump? I was planning on putting a SAE connector on it for use with my battery tender harness.

Easier to just buy one

Yes, I just built one. Simple to do. Why anyone with access to an old controller would opt to make a cable that
connects to the battery is beyond me.
PM me for instructions if you want.
Spending 30 or 40 bucks on a cable is not worth it, you can roll your own for free.

Very simple if you have access to one of the BMW special electrical connectors from a dead controller

Plug part numbers
 
The BMW part numbers for the conectors are as follows. :D

61-13-8-352-330 Blue plastic housing. Qty 1
61-13-0-007-571 Snap in receptical with wire. Qty 2

These are available from BMW automobile dealerships and cost roughly $12 for all. The wires are 19 inches long and snap right into the blue housing. All that is left to do is either put alligator clips on or install the plug of your choice to match a battery tender type plug.:clap

Cool! Can you please post a picture of it? Thanks.

You can look up pictures of the parts on a parts fiche on line.

A duff FPC is free, from that you can easily make a type of bypass that does not have to plug into your battery. Ask around and you will likely find an FPC that has gone south on someone. Having to disconnect the cable every time you stop the motor will get old fast.

How many fuel pump controller failures have people experienced? If you are on the road and it fails on you, can't you make your own bypass cable with your failed fuel pump controller connector?

Of course you can.
But to do that, you better be sure it is the FPC before you take out the cutters.
Having a ready to go cable will give some people who dont have the best troubleshooting abilities some peace of mind.
Others will appreciate the practicality of not having to do splicing again.

MTrider16 02-01-2013 04:33 PM

How many FPC have gone bad on the F800? If its a small number, I'll take my chances and trouble shoot the bike whenever I have a problem.

I never thought of making one for my 800.
However, I did, on a trip to Mexico, start thinking that I should learn how to make one for my 1200, as a lot of people said it would fail.
It did. Just moments after I was thinking about it.
However, I was able to get someone to come and lend me their spare.
What he had done was replace his controller before it went out. Then keep the original one as a spare.
I got a new one for myself, and used my old one to make a by-pass.
That way the cable does not have to pass outside the fairing and into the battery, as it does on the ones that you buy.
Most of those tap into the exterior (to the fairing) outlet for accessories.
That seems a dumb way to do it to me.

David's post above should answer any doubters.
I had thought of buying a spare but learned the Tim Cullis Morrocan bypass method and kept it as a PDF in my cel phone. Got me home when I was a couple hundred kms away in a mountain here where I live in Mexico.
If you have a black FPC, you might have better luck than a grey one.

Thank's!

This is the parts described by Moqui:

This is where to connect:

This is my version of a finished cable:

Please note that you can't power the pump from the stock outlet since it will shut down due to (I guess) the high power consumption from the pump.

And this is where my cable will hopefully rest in peace:

Lars:

Thanks!
Once the wires are inserted in the plug can the be (easily) removed again?
If not, I am thinking of leaving the plug unassembled to the wires ...

I recall Joel saying that sometimes "jogging" the pump back and forth a bit by reversing the polarity of power to it would get the pump unstuck... so leaving the wires free would more easily allow
the jogging routine...
