GlennWest Posted May 28, 2016 Report Share Posted May 28, 2016 Do any of you have 16 Guageish wiring on grounds with in line fuse? I do. Found one of them was wrong. Remote sensor for alternator was on ground and had fuse. It goes on positive for alternator reading charge. I have corrected with a new alternator, bummer, but have one more on ground with fuse. 2003 Teton Grand Freedom towed with 2006 Freightliner Century 120 across the beautiful USA welding pipe.https://photos.app.goo.gl/O32ZjgzSzgK7LAyt1 Link to comment Share on other sites More sharing options...
Alie&Jim's Carrilite Posted May 28, 2016 Report Share Posted May 28, 2016 Yes but it's on a Volvo. 1 wire to ground with a fuse. If wire is not attached or fuse blows the engine will turnover but not start. Found that out replacing batteries.

GlennWest Posted May 28, 2016 Author Report Share Posted May 28, 2016 Ok then. I won't trace it down. Nasty job.

RandyA Posted May 29, 2016 Report Share Posted May 29, 2016 The electrons in a DC circuit actually flow from the negative pole to positive. Most folks believe it to be opposite (pos to neg). Fuses or OCPD (over current protection devices) are usually placed in the positive side of a circuit since multiple grounds are often needed to reduce circuit noise, also simply by tradition and for shock protection. In a DC circuit with only one possible ground placing the OCPD on the negative side is perfectly acceptable, though somewhat unusual. Anyone on here remember automobiles that had the POSITIVE terminal of the battery(s) connected to the chassis GROUND?

beyerjf Posted May 29, 2016 Report Share Posted May 29, 2016 Positive ground 6 volt systems were more or less the standard procedure prior to the mid fifties. . Studebaker used 6V positive ground from the 1930's until switching to 12V negative ground in 1956, the same year Ford did the same thing. Lots of heavy duty trucks prior to 1960 used positive ground systems of various flavors. Series parallel switches with the starting circuit on either 12V and the rest of the system on 6V, or later 24V starting with the rest of the system on 12V. I had a 1974 White Road Commander(the company Volvo bought) with 4 6V batteries, 2 of them in series, then those 2 in parallel for a 12 V system. Nothing was uniform. Because of the ever sophisticated electronics, the truck manufacturers are tinkering with 36 V systems, but the customers are not ready for it.

I once walked into my shop to find my brother-in-law fussing with a neighbor's Farmall Cub. Every time he connected the battery, the motor would start turning over, even though the switches were "off". The generator was spinning the motor backwards. Kids..........

It's not just the "old" stuff that's goofy. I have "updated" my Deere tractors, from 2-6v in series, to 2 or 3-12v in parrallel, along with new cables, more, and better, grounds. I did my 4wd back in '07 and still have the same batteries. It spins better than when it was new, in 1976.\ My 1949 Farmall Super "A", otoh, still has a single 6v, pos. ground, and works fine.

Still have the 4020 with a turbo 120 plus hp. converted to 12 volt (it got old trouble shooting with 6 and 12 volt together). It's great around the barns or in a pinch!

Alie&Jim's Carrilite Posted May 30, 2016 Report Share Posted May 30, 2016 Jim - that is actually in the operators manual. Look in the 'starting after long storage' section. It says to pull the fuse and roll the engine for a few seconds. Builds oil pressure and runs it through the bearings. Thanks, I did not know that. I thought it was just another way Volvo makes you cuss in the pouring rain trying to replace batteries in a NAPA parking lot!
