What tools, materials, and equipment do I need when troubleshooting?

This article lists some basic tools and supplies that you should consider having on-site when performing system maintenance or troubleshooting activities.

These are some basic items that Carmanah recommends be available at the job site:


Smartphone or digital camera A smartphone can be very valuable in relaying product information to and from the Carmanah technical support team.
Battery tester
(for solar-powered systems)
For solar-powered systems, a dedicated battery tester is the best tool for diagnosing battery health.
Spare battery
(for solar-powered systems)
For solar-powered systems, a spare battery (even a very small temporary one) of the correct voltage can be very valuable in troubleshooting a system that is otherwise non-responsive.
Multimeter A multimeter is used to check electrical continuity and verify voltage readings at critical points in the system.
System fuses

Spare system fuses of the correct size and type are often required, and will in some cases eliminate the need for subsequent site visits. 

Troubleshooting tip: Some systems use more than one fuse, so be sure to check all fuses.
Product user manual Download and print or have an electronic version of the product user manual available before arriving at the worksite.
Assorted hand tools

Ensure you have a good assortment of wrenches, sockets, and screwdrivers (of various sizes and types).

Technical tip: Some Carmanah products use small, spring cage type terminal blocks in various locations for wire connections; a small blade screwdriver is recommended for making or breaking connections with the terminal type.
