Is the power steering switch unfused on the 1.9 Digijet? Is the same fuse location recommended? |
My knowledge of the 1.9 is limited, but I'd study the wiring diagrams for a fuse in the fuel pump / fuel injection system. If one isn't shown, I sure would install one in the unfused feed wire!!

It's a switched ground circuit on the 1.9L, the ground is taken from the alternator M5 stud on the side of it. _________________ Silicone Steering Boots and 930 Cv boots for sale in the classifieds.

Bumpity Bump considering “this should be promoted like fuel lines”
This has made it to my to-do list. Will likely go with a standard blade fuse so I always have spare. _________________ '91 GL - 2.1 automatic named Klaus for weekend adventures.

According to pages 42 & 43 from http://www.mk2g60.yolasite.com/resources/Digifant/...rt%201.pdf
There are many things unfused from the the "fuel pump relay" output (terminal 87) that are unprotected from shorts. ICU, PS switch, all 4 injectors, fuel pump and O2 sensor heater.

Yes, that is a very good idea for this. "Glow" fuses are maybe the best innovation for fuses since the fuse. _________________ This free advice is worth exactly what you paid for it.

There's been some more people with new to them Vanagons since the last time this thread was looked at so just bumping it to bring the title up to be seen again. _________________ This free advice is worth exactly what you paid for it.

Could this be a concern for any converted vans, be it Subaru, Bostig, Tiico, ALH, etc? |
The OE 1993 - 1995 wiring diagrams for the engine I used in my VW inline engine conversion do not show a PS switch as an input to ECU. AFAIK the engine management simply sees any change in idle (via cam position sensor?) then compensates for that.
I'd guess that most OBD1/2 engine management systems, thus conversions, behave in a similar manner. So that, and removal of the WBX wiring harness, remove that potential issue.
There are other OE wires in the Vanagon that are not fused. And, depending on how a conversion was done or what the OE wiring diagrams show, more unfused 15 or 30 buss wires could end up being installed. In regards to those wires becoming a potential issue, it all comes down to the quality of conversion work that is done.

I think having a fuse is not a bad idea. But doing this makes a more secure connection that is not hampered by a lack of room. When using this with proper connectors you no longer have to worry about those stupid flag connectors.
You can use the factory flags or just lob them off and use a good quality open barrel connector with a clip on cover.

I installed a fuse but because having a fuse is NOT expected by anyone, I clearly marked the box with a label clearly stating that there is a fuel injection fuse.

That's a really good idea. I had a friend wash his engine bay and then his van wouldn't start. Took a long time to remember that fuse was installed and of course it was the reason it wouldn't start. It did it's job! |

No, that spot would only protect the fuel pump wiring.
The spot to protect everything is on a previous diagram page, where the current track 5 box next to your arrow leads to.
Look for a circle with P1 and a connector labeled T2m.
The fuse goes in the red wire between those points.

Thanks Mark!

Yesterday I added insulation to the power steering contacts.

I would suggest that everyone install a 7.5 amp inline fuse for the fuel injection / fuel pump circuit.
It is cheap insurance warding off potentially big problems.
Keep in mind that If the fuse does blow, your engine shuts off.
But for me, better that than a fire!

On my “to-do” list today!
Here’s the quality install I’m aiming for;

FWIW: Member farfromslow recently posted a pic of a perfect install:
- nice heat shrink on connectors...
- clear fuse holder (assume for "glows-when-it-blows" type fuse)...
- nothing more or less than needed...
Git 'r done!

Seems like an excellent idea (thinking of future owner -me- lying in a puddle in the side of the road changing out a fuel pump - to no avail)
My question is this the proper spot in the Bentley - 97.124? Pretty sure it is, but would like to post the correct spot shown in farfromslow’s post above. ‘91 2.1l auto (Canadian)
