Hello,

I've been browsing the web for days trying to find what's wrong with
my backup lamps which are not working when I back up. I've cheched the
whole circuit up to the neutral safety switch (I have an AW-4
transmission) - the reverse switch is acting okay when reverse is
engaged. I have a brown with a green line going to the lamps from the
safety switch plug and on the other side a blue with a white line. I
can turn on both lights if I apply 12V to the brown green wire.

I suspect the blue/white is not powering the light so my questions
are :
- is this one connected directly to the battery or the computer ?
- are there any fuse I may check (so far I haven't found any visible
ones related to this switch ?
- is it possible to bypass the blue wire by connecting it directly to
the battery ?

Any help will be appreciated ! Thanks !

Lionel

 

I admittedly know "0" about which wires go where, but I would warn you
that applying current where there is none can be a VERY bad thing. I
would get a wiring schematic and backtrace until I found the problem
and repair it correctly.

Good Luck, Bruce

It probably doesn't matter, but what 'kind' of Laredo do you have. I
have a CJ7 Laredo and love it.

Meanwhile is sounds like you have a bad connection in the switch. Some
of those switches are extremely expensive. Here is a link on rebuilding
one kind of them:

It's a Cherokee Laredo 2.5L. I am working a lot on this vehicle I've
been using now for a couple of months. I love this vehicle.

Thanks for the link. I believe the switch is okay as I've already done
the continuity test the article mentions . I've checked the "reverse"
pins (A-E) on the switch and I have no resistance when reverse is
engaged (circuit is closed) and no continuity when reverse is not
engaged (circuit is open) so I assume the switch is doing its job. The
Haynes manual mentions the wire before the switch is hot at all time.
By "hot", my initial question was to know if I can connect it directly
to the battery. So far I haven't found 12V on this wire so I am
tempted to bypass this wire but I prefer to be sure before doing that,
I won't kill the safety switch. As pin "A" is also responsible for
1-2nd speed and 3rd, is there a way to test those modes are engaged ?
The differences between D, 1-2 and 3 are not striking a lot to me so
far. I guess I should be feel a difference and so far I am not.
