[xj40] current drain RHS fuse 10


(Dan) #1

Hello all,

I’ve found that fuse 10 in the RHS fuse box is imposing
about 130 milliamps of static load on my battery. The
maintenance handbook lists the 20 amp fuse as protecting
‘‘radio, sunroof, heated door locks, glove compartment lamp,
map light, interior headrest lamps, ‘state’ illumination’’.
I’ve ruled out all of those via either disconnecting the
equipment or visual verification. Haynes does not provide
any information about what other devices might be on this
circuit. What else is a likely culprit? (boot and glove
box lamps have been checked)

Thanks,

Dan

Dan,

I believe others have experienced problems with the door
lock heater causing heavy current drain.

Have you tried pulling the door lock heater relay tosee if
that stops most of the 130 mA drain? It’s the one in the
black base at the foot of the ‘A’ pillar on the passenger
side with Brown/white, Orange and Slate wires going to it.–

Bryan,

Found the relay and it was warm to the touch. Removing it
reduced the total static load to 30mA. I’ll have to look at
the lock heaters next time I have the doors apart. I presume
there’s a microswitch in there that needs cleaning and/or
adjusting.

Thanks for the tip,

Dan–

I didn’t find any relè under the passenger’s Seat…someone can post some photo about this position? Thanks

The door lock heater relay is not under the passenger seat, it is the one as described under the passenger side dash at the base of the ‘A’ pillar (That’s the body frame between the windshield and the front of the passenger door)

Can you show me in this photo? How you Can see someone put hands in all Electric system…i bought so.

From memory (and I no longer have a car to confirm this) the relay is not shown in your picture but is further outboard at the base of the ‘A’ pillar behind the trim panel in the footwell forward of the fuse box. Perhaps someone with an '87/88 will confirm that.

Behind the fuses on right side at floor level. Need to remove panel for access .

6e1847cd4f6b0926b95f64aaa9063b49ffbc72e4_1_666x500 you speak about that position signed with the red circle or other behind that big black box fulled of electric circuit…

What Is and where this A pillar??? :open_mouth:


(Robin O'Connor) #11

The car has ‘A’ ‘B’ and ‘C’ pillars these are ‘A’ in front of the front doors.
‘B’ pillar separates the front and rear doors.
‘C’ pillar is at the rear of the rear door.


So you are looking for the corresponding area inside the car.
Hope this helps.
