Your Coleman Mach AC unit on the 2019 Rockwood Minilite 2509s has developed a short circuit that's drawing power even when the AC is off. The fact that the fuse blows before it's even fully seated indicates a direct short to ground in the AC circuit.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
For Ford F53 chassis, look for existing rubber grommets near the brake pedal assembly or steering column area. You can also use the main harness grommet where factory wiring passes through the firewall.
You likely have an incompatible control box model. The 9430A751 with dual SIG terminals is designed for true multi-zone systems, while your single-zone setup needs a simpler control box with one SIG terminal.
Surge Guard 40250-RVC and 40350-RVC are interchangeable. Buzzing usually means loose connections - tighten all terminals. If buzzing persists with tight connections, the relay may be failing and unit needs replacement.
Yes, you can remove inverter/charger and install standalone battery charger. Much less expensive than replacement inverter. Check if inverter includes transfer switch - you may need to address that. IOTA or Progressive Dynamics chargers work well.
Rear ABS sensor at hub or differential depending on system. Remove wheel for access. Use penetrating oil on mounting bolt. Clean tone ring during service.
Essential guide for Ford E-Series Class C motorhome chassis covering suspension, maintenance, and common issues.
A voltage drop from 12.5V to 10.3V under load indicates excessive resistance in your headlight circuit, likely from corroded connections or undersized wiring. This significant drop explains your dim headlights and requires immediate attention for safety.
Coleman Mach heat strips can be added using the Heat-Ready Control Box. This adds electric heat through your AC while keeping furnace independent. Verify AC model compatibility and check electrical capacity - heat strips draw significant amps.
Apply penetrating oil and let soak 24-48 hours. Work adjustment gently. Electric cables disconnect at plug connector behind mounting surface. Replacement mirrors available if needed.
Underhood generators and idling work but check local idle regulations. Extended idling wastes fuel and causes engine wear. Solar, generators, or DC-DC chargers are better long-term solutions.
Ford V10 coil bolts fit better with 9/32" SAE wrench. Access cylinder 3 by removing doghouse and working from inside RV. Use wobble extensions and swivel sockets for tight areas.
Shutting down under load after rebuild suggests carburetor still not delivering enough fuel or governor sticking. Watch governor arm movement during load test. Try gradual load increase to find threshold. Check fuel pump output if equipped.
Yes, high-output alternators can be installed on your F53/Triton V10, but you'll need to upgrade wiring and possibly the serpentine belt system. The Tucson unit you found is a solid choice for your large inverter battery bank needs.
