In addition to the main fuse wire (Fusible Link) in the engine compartment, there is a main fuse box under the dashboard.

Overview
USA 1972 Owners manual (see pages 35 for fuse information):
If a fuse needs to be replaced, refer to the specifications listed on the fuse box cover.
Fuses
B110 uses the standard cylindrical fuses used by all cars until around 1980. The numbers are:
IG: Ignition Switch Circuit (only HOT when key is in IGN position)
- 'W' 15 AMP Wiper, Washer, Heater
- 'M' 10 AMP Meter, Reverse Lights, Alternator Regulator
Battery/Alternator Circuit (always HOT)
- 'L' 15 AMP Head Lamp
- 'PT' 10 AMP Park lights, Tail lights
- 'C' 15 AMP Radio, Clock, Cigarette lighter, Room lamp
- 'H' 15 AMP Horn, Stop lights, Hazard lights
There are also two empty holes in the fuse box to hold two spare fuses.
Location
It is located under the dash above the driver's right knee. It is bolted to a bracket on the bottom of the dash frame:

Variations
#1 (2nd source - up to '71-Mar) ___ 10A (w/o headlamp fuse) 15A 15A 10A 15A
#2 15A 10A (with headlamp fuse) 15A 15A 10A 15A
#3 20A 10A (620 type: headlamp changed to 20A) 15A 15A 10A 15A
Wiring
The wiring harness has individual connectors to the Fuse Box:
15A C Fuse: Cigarette Lighter, Radio, Clock and Room Lamp
Fusible Link
The Fusible Link ("Main Fuse") connects to the POS battery terminal about six inches from the battery. The fusible link is a special length of wiring that will melt if its rating is exceeded and is there to stop the electrics if the car is drawing too much power, like an open short circuit.
See main article: Fusible Link
Cleaning
If your fuse box gets HOT or starts melting (but the fuse does not blow), then CLEAN the fuse box. Soak it in vinegar for 10 minutes.
Or if you are getting electrical equipment not working, clean the fuse box.
Why? Dirty connections cause undue resistance, eventually leaking to this:
The reason that fuse lead is getting hot is because of resistance. This is pretty common with old-styled glass fuse boxes. You get resistance at either the fuse itself, or the connection between the fuse and the terminal - along with whatever other resistance is present in the wiring. The corrosion is at the fuse box connections, which is why it gets hot, and why it melts.
- Disconnect the battery
- Remove all the wires from the fuse box (take a photo first, or write them down carefully which is which)
- Take the fuse Box in the house and soak it. Fill a small bowl with distilled white vinegar from the grocery store. Soak for 10 minutes.
- Rinse with water with a little Arm & Hammer mixed in to nuetralize the acid from the vinegar. Then rinse with plain water
- Let dry thoroughly/overnight
- Put a little dielectric grease (a LITTLE not a LOT) on each copper terminal (front and back of fuse box) to keep moisture corrosion minimal
