When it comes to maintaining your 1986 Toyota Pickup, one of the key components you'll need to keep an eye on is the fuse system. Fuses play a critical role in protecting your vehicle's electrical circuits from overloading, which can prevent expensive damage. Understanding how to handle fuses can save you time, money, and hassle. Here are four essential tips to manage and maintain the fuses in your 1986 Toyota Pickup effectively.
Understanding the Fuse Box
Before diving into troubleshooting or replacing fuses, it’s essential to understand where your fuse box is located and what each fuse controls.
-
Location: Your Toyota Pickup has two fuse boxes. The primary one is located under the dashboard on the driver's side, while another, less accessible, is found in the engine compartment, near the battery.
-
Fuse Diagram: Always refer to your vehicle's owner’s manual or the fuse box cover for a diagram. This diagram will illustrate which fuse corresponds to which circuit or electrical component.
Examples of Common Fuses
Here’s a simple table showing some of the common fuses and what they control:
<table> <tr> <th>Fuse Label</th> <th>Rating</th> <th>Function</th> </tr> <tr> <td>HEAD (R)</td> <td>15A</td> <td>Right Headlight</td> </tr> <tr> <td>HAZ-TRN</td> <td>10A</td> <td>Hazard Warning Flashers, Turn Signals</td> </tr> <tr> <td>IGN</td> <td>7.5A</td> <td>Ignition System</td> </tr> </table>
Identifying a Blown Fuse
When an electrical component isn't working, a blown fuse might be the culprit. Here are steps to identify and replace a blown fuse:
-
Check the Component: Identify which electrical component is not functioning as expected.
-
Inspect the Fuse: Use the fuse diagram to find the correct fuse. Look for any visible signs of a blown fuse such as a broken filament or discoloration.
-
Replace if Blown: Use a fuse puller or needle-nose pliers to remove the fuse. Replace it with one of the same amperage rating. Never use a fuse with a higher rating as it can lead to circuit damage.

Testing and Troubleshooting Fuses
Not every electrical issue means a fuse is blown. Here's how to troubleshoot:
-
Turn on the Component: If the component stops working, turn it on. If it doesn't work, the issue might be with the fuse or the component itself.
-
Use a Multimeter: If you have access to a multimeter, set it to the continuity or resistance setting. Touch the probes to the fuse prongs. If it shows zero resistance, the fuse is good. If not, it’s time to replace it.
-
Trace the Circuit: If the fuse checks out but the component still doesn't work, trace the wiring for breaks, corrosion, or loose connections.
Common Mistakes to Avoid
-
Replacing with Incorrect Rating: Using a higher-rated fuse can bypass safety features, potentially causing electrical fires or further damage.
-
Not Investigating the Cause: Replacing a fuse without understanding what caused it to blow can lead to a cycle of replacements. Always check for underlying issues like a short circuit.
Advanced Tips for 1986 Toyota Pickup Fuse Maintenance
-
Regular Check-Ups: Inspect your fuse box every few months for any signs of wear or corrosion. This proactive approach can prevent sudden electrical failures.
-
Keep Records: Note down which fuses you have replaced, when, and what problem they were associated with. This can help diagnose recurring issues.
-
Backup Fuses: Install an additional fuse box for aftermarket accessories like aftermarket radios or lights. This ensures that your factory fuse box isn't overloaded with extras.
