The Monsoon is a fully waterproof voltage indicator with a bright three colour (green/amber/red) LED. The control circuit is built into a tiny water-resistant capsule embedded directly behind the LED, and a black nylon bezel (plus one spare) is supplied for a tidy installation into your panel.

Applications include:
Below are our standard thresholds, recommended for all 12v lead-acid battery systems including an alternator or other charger. Completely bespoke thresholds and output patterns can be created for you at no extra cost (e.g. for custom or ultra-low power applications).
Interpretation: | ||||
Voltage: | Output: | Engine running: | Engine stopped (electrics off): | |
>15.20v | ■■ | Green / Red alternating | over-charging – regulator problem | not applicable |
>13.20v | ■ | Green steady | normal charging | exceptional battery charge (uncommon) |
>12.45v | ■ | Amber steady | under-charging – alternator problem | normal battery, charged and in good health |
>12.25v | ■■ | Red slow flashing | not charging – battery low | fair battery charge |
>12.05v | •• | Red 2 flashes, repeating | not charging – battery low | low battery charge |
>11.80v | ••• | Red 3 flashes, repeating | not charging – battery very low | very low battery charge |
<11.80v | •••• | Red 4 flashes, repeating | not charging – battery very low | consider renewing battery |

(e.g. headlights)
** a very small number of users confuse the amber and red colours. However, amber is always steady, reds are always flashing
