First, I have read everything already posted on how to wire a backup LED using the Reverse Switch to make/break the ground to have the LED turn ON when the transmission is shifted into Reverse. I understand the recommended approach. I also have the factory service manual and can read the wiring diagrams. I have done far more complex automotive wiring jobs on other machines. This seems straight-forward...but it’s not. I ran a temporary ground wire to the Reverse Switch connector at the bottom rear of the engine making sure that wire is NOT accidentally grounded to the engine case. It is not. With the transmission in Neutral (or Drive), there is no continuity between that wire and ground. This is good. To put the machine in Reverse, with the engine running and the trans in Neutral, you pull the small ”P/R lever” on top of the rear brake lever rearward and pull the rear brake lever, then depress the transmission downshift switch. At that point the trans goes into Reverse, the digital display shows “R” and I get continuity on the temporary ground wire and my LED turns ON. All this is good. However, as soon as I release the brake lever the LED goes OFF even though the machine is still in Reverse. My volt/ohm meter shows I lost continuity to ground on the temporary wire. As soon as I pull the “P/R“ and brake levers, I regain the ground. This makes no sense to me as the transmission is still in Reverse. My intention is to have the LED stay on as long as the transmission is in Reverse without needing to have the brake partially engaged. What am I doing wrong or is the wiring or the Reverse Switch on the 2019’s different than what is shown in the 2014-2019 Service Manual? Everything else on the machine works as intended. Any constructive suggestions will be greatly appreciated!
