YOU ASKED IT-- NO GASKET Dear Half-Mast, Is there supposed to be a gasket inside the cover on the intervehicular cable that sends electrical power from a truck to the trailer it's pulling? SSG N. D. Dear Sergeant N. D., I You bet not. If you come across what looks like a gasket inside a trailer re- ceptacle cover, it's a homemade job. With a gasket inside the cover, and the cover shut, water and stuff can get in- side through the indexing slot. The spring keeps the cover tight against the connector, without adding a gasket- believe it. The receptacle on the truck is another story. It's made in a different way ... so the cover needs a gasket. vd-jfo BRAKE BETTER THAN BREAK Never let it be said that you didn't know be- cause here's the word now-when you park your multifuel or diesel truck, make sure the gearshift is in neutral and handbrake on. Why? Multifuel and diesels are compression ignition engines, that's why. So with the trans- mission in gear, the engine can be turned over and started by pushing the vehicle. And an acci- dental push could mean a repair job for anything that might get in the way of the vehicle-like people and things. In other words, use your parking brake when you park your multifuel or diesel truck. Never . never NEVER park with the transmis- sion in gear. iE liA USE D~~M RAKE! TRUCK RECEPTACLE HAS GASKET ...NOT 50O IN TRAILER COVER.
