Multimeter
This is the starting point. NO Boat should EVER be without one. The photo on the left shows a slightly more advanced model with a built in clamp-on ammeter to measure AC and DC amperages. It is perfect to verify proper operation of an alternator's output, a battery monitor's displayed information, or as a backup in the event of instrumentation failures.

Battery Load Meter
On a large battery bank (800+ Ah) one is able to pull 30-50 amps sometimes with a worn out/exhausted battery or battery-bank for 1 to 3 years after the battery or battery-bank should have (already) been replaced. That same exhausted battery bank will not be able to supply a high draw (100-150amp) load such as running Air Conditioning. This is usually the first time a user "discovers" that his battery bank is going bad and "needs" replacing. In reality, the battery / battery-bank typically went bad 1 to 3 years in the past, but the boat owner never knew it because he never performed load tests (at least quarterly), kept records using his battery monitor, does not have a battery monitor installed, or ever even used/ran high loads from his battery bank as part of normal operation. The photos to the left show a standard 100 amp load meter (black instrument) and a selectable higher capacity 500 amp load meter in the other (blue instrument) photo.

Belt Tension Gauge
This tool is used to set and check the tension of your belts. It works on v-belts and serpentine belts. If you set your belt tension only by feel or eye, IT WILL NOT be correct. Usually, it is on the low side and not close. A belt that is too loose will cause equipment damage due to excessive heat generation. A belt that is too tight will cause equipment damage due excessive side loading and possible pulley or bearing failure. For additional information, Click Here to see the pertinent FAQ. |
