I was thumbing through a dealer's service book for an S series tractor and on the battery maintenance page it mentioned a precaution in taking hydrometer readings from a No-Over-Flo battery. To quote from the book; "When taking hydrometer readings on batteries equipped with No-Over-Flo it will be necessary to return all electrolyte withdrawn from battery for purpose of reading, by depressing lead washer. A shoulder on stem of Exide S-1-B hydrometer is provided for this purpose. If other type hydrometer is used depress washer with end of hydrometer tube. CAUTION: This washer should be depressed only when returning electrolyte to cell; not when filling with water".
My curiosity is getting the best of me. How was this battery different from a regular battery? Also, where is the tail light mounted on a 48 SC? Fender? Jim

I suppose the seat suspension action makes and breaks ground. Whenever I do find an appropriate light I will run a separate wire or thin graded strap to ground. Today I'm rewiring it completely with cloth covered wire. The wiring on it is modern vinyl insulated and works OK, but darn it, it has to look right. This old girl is my pet and I have been neglecting it by not having the wiring up to snuff. Jim

SC tail lite? My SC had no lites from the factory. When lites were added, the tail lite was mounted like the DC s, on the rear of the seat bracket.Always had trouble with the grounding, it flickered quite often same as our DC s. clint

The genny has trouble keeping up with two lights so a third one might be too much of a strain on it. I'll have to take a look at the positioning of the third brush. Now, to find the proper looking tail light for the old girl. Jim

This one's a 48. It hasn't had a rear light for many years and really doesn't need one but I would like to have one there 'just because'. I would think it would be vibrated to death on the fender. If it's behind the seat it might get in the way for swinging my leg over the seat. I don't kick as high as I used to. LOL. Maybe that's why I can't find any pics of one with a rear light. Jim

The flat z bracket goes down so not much chance of your foot getting it. When I was a kid I plowed after milking with a 48 SC. My experience was, the lites aren't very bright on a dark nite.

Thanks. I looked at a zillion pics of SC's in tractor photos and only a couple showed the back of the tractor. No light was present on those two. Nobody wants to take a picture of the back of a tractor, understandably. This winter I had to make a complete drawbar assembly for a 10-20 Mogul from scratch, only going by pictures. Finally found a rear pic of one but it took a bunch of searching on the net. Jim

Rear lite goes on a Z shaped bracket on the back of the seat. The wire threads thru the seat channel with a small bracket to keep the wire out of the suspension spring.

There are three variations of SC rear light mountings, that I know about. Early tractors had the tail light mounted on the fender. I think that this was changed early in 42'. Later tractors had the tail light mounted to the seat channel. Before 52', there was a flat z-bracket under the seat, and eagle hitch tractors mounted the light to a small l-bracket which also held the top pin for the top-link when it was not in use.
