12V Install Tools & Testers

Check My System

Answer a few quick questions about your 12V setup and get a checklist of what to confirm, what you may be able to keep, and which guides will help.

This is a plain-English checklist, not an electrical design or safety inspection. It works out what to confirm from your answers. Nothing you enter is saved or sent anywhere, and you don't need to know every detail. Choose "Not sure" or leave a box blank.

What's your setup?

About this check

  • The report is based only on your answers. It can't see or test your equipment, so it doesn't certify that your system is safe, check your wiring or fuses, or guarantee that parts will work together.
  • It doesn't use manufacturer specifications. Always check your equipment manuals, and ask a qualified auto electrician when you're unsure.
  • Any work on 240V AC wiring, including inverter outputs, mains inlets and shore power, must be done by a licensed electrician.
