light switch

Can anybody tell me what the amperage of the light switches is on the 06 56 66 series tractors?

Have no idea what the engineering specs are but from my experiences with a number of 06,56 and 66s

They are fused at either 15 or 20 amps.

The max stock loading that I know of was 5 4411 or equiv 35 watt sealed beam lights. This is about a 15 amp load.

Extended use at this 15 amp load will eventually overheat the battery terminal causing it to rust (they are made of steel not brass) resulting in a poor connection which causes even more heat.

If you plan to add any additional lights, run them from a relay.

One expensive solution is to change to LEDs. Hope this helps.

15 amp is #14 wire
20 amp is #12 wire

I was putting led's on since the others don't work and the wiring is in poor condition. A 24 inch light bar in front and in back. Thought maybe I could use the original switch for that load and skip the old 4411's. They are like holding a candle out there for light compared to the led's.
I had forgot they had a 15 or 20 amp fuse in the light line. Thanks.
