Finding discontinued Generac 75D coolant hose C4845 requires checking specialized generator dealers, industrial suppliers, custom fabrication shops, or cross-referencing with similar models. Generic coolant hoses can often be adapted with proper sizing.
Your 1993 American Eagle's Onan generator producing only 12-15 volts indicates a faulty rectifier bridge (part CR21) or suppressor (part RV21). The correct replacement parts are 305-0696 for the rectifier bridge and 305-0703 for the suppressor.

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.
Even with disconnect switches engaged, phantom loads and battery self-discharge can drain RV batteries during storage. Installing battery maintainers, using master disconnect switches, and addressing phantom loads will solve this issue.
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.
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.
Your RV ATS isn't transferring shore power to your AC system due to likely faulty internal contactors or control board issues. This typically requires professional repair as ATS units contain high-voltage components and complex switching mechanisms.
Worn Onan 10KW generator mounts cause vibration and noise. Replace with OEM parts from Cummins dealer. Most owners have shops do this due to generator weight and access challenges.
Generac oil drips after breather hose replacement suggest other issues: check oil level, breather valve, hose routing, and valve seals. Clean engine and observe where oil first appears.
Built-in Southwire surge guard EMS provides comprehensive protection including surge, voltage monitoring, and fault detection. External unit unnecessary if built-in is full EMS. Verify yours has EMS features not just surge protection.
Cummins in RVs are diesel engines or Onan generators. Gas chassis use Ford or GM. Cummins diesel and Onan generators need regular maintenance.
