Engine Brake Switch

The engine brake switch controls the degree of engine braking. Normally there are two paddle switches, a two-position On/Off Switch to activate the engine brake, and a two-position Hi-Lo Switch to control the amount of engine braking.

To turn the two-position On/Off Switch on, raise the paddle. When the two-position switch is on, an amber light-emitting diode (LED) illuminates inside the switch.

To turn the two-position Hi-Lo Switch on high, raise the paddle. To turn the two-position Hi-Lo Switch on low, lower the paddle. See Fig..

Hi-Lo Switch

Fig. 1, Engine Brake Switches

A three-position switch is used on MBE900 engines equipped with both the regular engine brake and the constant-throttle (decompression) brake. It works the same as the two-position Hi-Lo switch, except that there is a third (off) position when the switch is left at its normal position.

When the panel lights are on, the Hi-Lo icon is backlit in amber on the three-position switch. On both the three-position switch and the two-position switch, the ENG BRK legend is backlit in green when the panel lights are on.
