ELECTRICAL FEATURESaccompanying figure.Be careful when working around these connections as an accidental electrical short to ground (i.e., momentarilyconnecting the “positive” or “hot” terminal to any part of the chassis) can be hazardous and harmful. Towardsthis end, don’t store in this particular storage compartment anything which may move around in transit andsubsequently cause any electrical short circuits or anything that is flammable.Fuse BlocksSome of the electrical circuitry within the motor home is protected by various fusing systems. Some of thesefuse blocks are immediately accessible from the driver’s side underneath the dashboard.The electrical circuits protected by the under-dash fuse block (Figure 7-12) include: headlights, panel light fordashboard, tail lights, optional jacks, turn signals, cruise control, engine computer, accessory fuses, heater anddash air conditioning.Figure 7-12. Fuse BlocksAdditionally, there is another chassis fuse panel which works in conjunction withthe chassis fuse panel and provides comparable protection for the above-listedcircuits.Locatedbeneath theaccess panelon thedashboard(Figure 7-13)are two additional, fuse panels; thesepanels protect the following electricalsystems: mirrors, optional satellite jacks,camera, optional power windows, dashtrim, lighter, map light, optional powerseats, and radio.Figure 7-13. In-Dashboard Fuse BlocksShould there be any electrical failure ofthese components or systems, the first troubleshooting procedure should be to check the fuses and haveavailable replacements to replace any blown fuses, as may be warranted.As an aid to extracting and/or installing fuses in the fuse blocks, one may wish to buy an inexpensive fusepuller at any electronics or hardware store. This useful tool makes the installation or removal of fuses mucheasier and prevents inadvertent damage to nearby fuses or the fuse block itself.Whenever a fuse has been “blown” and is to be extracted and replaced, it is good practice to examine the wiringgoing to that particular fuse to see if there is any noticeable degradation (e.g., wiring insulation nicked, missing,or melted) which may indicate damage beyond the fusing proper.7-9
