Replacing a TR-1 Gladiator Deckmount Switch
Since Garmin no longer carries TR-1 Gladiator parts, if a deckmount switch needs to be replaced, a third-party brass momentary switch can be used. Review the diagram below:
The Blue goes to the Deck light, the Black is the positive and goes to the Deck Switch, the White and the Brown both go to ground.
