Victor 86B Fuse Replacement Guide
So you can avoid the hassles I had the first time I opened mine up!
Compliments of Javaphile

First up is getting the protective yellow sheath off.
The yellow sheath is held in place by snapping into two grooves on the
front of the meter. This picture shows the location of the two grooves on
the face of the meter.

To remove the yellow piece pull it away from the top of the meter (The
dark blue arrow.) so it clears the optical output. To get it out of the
grooves work on one side at a time starting at the meters widest point
(The middle lighter blue arrow on either side.). I found it worked well to
hold the meter with both hands with the fingers underneath it and the
thumbs resting on either side at the widest point and then pull it away
one side at a time with the ball of the thumb and working it out moving
towards the top until you can get it off the corner. Then repeating it on
the other side, making sure to hold the first side removed so it doesn’t
pop back into the groove. Once both corners are free it’s then a simple
matter to push up with your fingers while pulling outward with your
thumbs and working it off going down the sides until it is off almost to
the bottom. Then grab the top of meter in one hand and the yellow piece
in the other and pull the meter out of the bottom of the yellow sheath.

Next turn the meter over and using a PH-1 screwdriver/bit remove the
battery cover screw (Indicated by the green circle.), the battery cover,
and the batteries.

Next up is removing the 4 case screws using a PH-2 screwdriver/bit.
With those screws removed the back case half can easily be removed.
The optical jack will most likely come out at the same time, set it aside
along with the removed case half.

Now comes the main reason for making this guide. Using a PH-1
screwdriver/bit remove the 4 screws circled in green. Do not remove the
7 screws circled in red. I repeat.
DO NOT REMOVE THE 7 SCREWS CIRCLED IN
RED!

Before removing the circuit board note how the two wires connecting the
battery holder to the board are routed. They are routed through a slot in
the side of the battery compartment so they aren’t pinched when the rear
case half is screwed on and will need to be put back there during
reassembly.
Once those 4 screws have been removed lift up on the circuit board
where the yellow arrows in the picture are, and by using a slight rocking
motion remove the entire assembly. There will be a bit of force needed
as you are separating the front dial from its contact assembly which is
mounted on the circuit board. Take it slow and easy as if you use too
much force not only can you damage the circuit board but when the
pieces suddenly separate there are several parts that can go flying.
Once the circuit board is removed do not move the contact assembly
or the front dial!
If you turn the circuit board over you will clearly see the two fuses on it.
Both can easily be removed from their holders and replaced as needed.
Note that the fuses have different ratings so make sure you’re using the
correct replacement fuse.
When reassembling the meter you will need to press the contact
assembly back onto the front dial. As long as you haven’t moved either
the contact assembly or the dial this is easily accomplished.

Reassembly
To reassemble the meter, begin with the front case half laying on its
face. Then make sure that the clear plastic piece that protects the LCD is
properly seated in the front case piece. Next make sure the 4 liners for
the leads jacks are in their appropriate holes. (Those 5 pieces are the
ones that can go flying if the circuit board was removed with too much
force.)
Next gently position the circuit board back where it belongs in the front
half of the case. Once it is properly situated press the post of the front
dial back into its contact assembly by holding the meter in your hands
and pressing on the middle of the dial with your fingers while your
thumbs press down on the circuit board directly above the middle of the
dial. The post will pop back into place in the contact assembly and the
circuit board should now be sitting all the way down on the posts the 4
screws that hold it in place screw into. If the circuit board is not sitting
on those 4 posts check to make sure the LCD protective cover is
correctly seated and that the 4 jacks and their red/black liners are
properly seated.
Now you need to put the optical output jack back on, making sure that
the LED is fully inserted into it and that the jack is properly seated in the
slots in the front case.

Note that with the exception of the battery cover screw all other screws
are screwed into just plastic. Screw them in snug but do not over-tighten
them or you will strip the posts they screw into!
Reinstall the 4 screws that hold the circuit board in place.
Holding the rear case with the inside facing down pull the battery
removal ribbon and the battery holder up through the opening where the
battery cover goes. Then place the rear case over the reassembled front
case and circuit board making sure the wires from the battery holder are
properly routed through the slot in the side of the battery compartment.
Reinstall the 4 large screws that hold the two halves of the case together.
Reinstall the batteries and the battery cover locking it into place with its
screw.
Put the bottom of the meter into the proper end of the yellow protective
piece and press it into place. Then work your way from the bottom to the
top of the meter pressing the meter back into its protective sheath. Once
the meter is completely pressed back into the yellow sheath press its
sides in and finally press down on the front of it to make sure it is fully
seated back into the grooves in the case.
Congratulations! You’re all done and your meter should once again be
fully functional! Enjoy!
