dmulhall Posted February 18, 2012 Report Posted February 18, 2012 so I am working at a friend of mine's garage. In his infinite wisdom he is looking at my engine and says "why is your coil mounted upside down?" "You never mount a coil upside down, there is oil in there and it doesnt cool properly"..."I said, I dont know, thats the way it has always been, never had any trouble with it..??" Should I be turning it around in the bracket and making it work?? anyone else heard of this, or what do I use as a deflection? haha Quote
Plymouthy Adams Posted February 18, 2012 Report Posted February 18, 2012 ask him the definition of hermatically sealed components.. Quote
JBNeal Posted February 18, 2012 Report Posted February 18, 2012 I reckon yer friend ain't heard of one of the unique features of the Dodge flathead ignition coil in that they only work well when upside down, kinda like the bottles at the water cooler or a hummingbird feeder. Technically speaking, the coil's efficiency is increased when the lead to the distributor/spark plug is as short as possible to reduce load losses. Some of today's car's have a coil plugged directly into the spark plug to eliminate the coil/plug wires entirely. Quote

NiftyFifty Posted February 19, 2012 Report Posted February 19, 2012 I always thought they looked goofy upside down, but have seen many didges and other old jobbies like that...I'm a right side up kinda guy myself....no point taking a chance my coil with will fall out Quote
Dodgeb4ya Posted February 19, 2012 Report Posted February 19, 2012 I put a new Echlin coil in my 1953 Plym wagon (correct factory way pointing down) and the oil in it dribbled all over the Dizzie cap! A week later the car died. Put a NOS MoPar coil in it and all was good for the rest of it's working life. Today all my cars have the best quality coils I can find and all are sitting upright in a nice mounting bracket away from the engine to stay cool. They don't leak and are more reliable than the 60 year old NOS MoPar coils I've had current issues with. Bob Quote
seabee1950 Posted February 19, 2012 Report Posted February 19, 2012 Long long ago when I was young and knew just enough to get the old car to fire we would put the coils and many other things in with bailing wire as none of us had a shop or even a garage and I didn't miss to many Fri night cruising with my sweety. Now looking at pictures of many old Plymouths 218's seems to be the factory way to mount them. 100_0169.jpg Quote
Desotodav Posted February 19, 2012 Report Posted February 19, 2012 They must have come that way from the factory. Here's a NOS one on Ebay with the stickers upside down (up the right way)... http://www.ebay.com.au/itm/COIL-NEW-OLD-STOCK-1930-40s-DODGE-PLYMOUTH-CHRYSLER-FARGO-TRUCKS-/280826375318?pt=AU_Car_Parts_Accessories&hash=item41628e6c96#ht_525wt_1163 .
