Mutley Posted January 7, 2019 Share Posted January 7, 2019 Defender 300300Tdi 1995 At the battery the there is 12.4 Volts At the Fuse box the Voltage is 11.5 Volts A drop of 0.9 volts Where and what do i need to be looking at to increase the Voltage at the fuse box?

monkie Posted January 7, 2019 Share Posted January 7, 2019 What do you get at the connection from the battery positive to the starter motor terminal? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 7, 2019 Share Posted January 7, 2019 The connector block that feeds into the main bulkhead loom can be quite crusty. Mine was shagged so I removed it and took the opportunity to feed each of the big brown wires via a 20A fuse, as LR don't fuse this by default and it gives me the heebie-jeebies; Big red wire is from starter motor B+, old brown wires into main bulkhead loom on the left.

Mutley Posted January 7, 2019 Author Share Posted January 7, 2019 @monkie...... will check, at work at the moment, so i will look in the morning. @FridgeFreezer.... ok again will check tomorrow. Do like that set up maybe a project job to do at some point. Quote Link to comment Share on other sites More sharing options...
Mutley Posted January 8, 2019 Author Share Posted January 8, 2019 FridgeFreezer where abouts is that block connection? I can't find anything that resembles that in your photo. Have looked all along the bulk head in the engine bay. Andy Quote Link to comment Share on other sites More sharing options...
western Posted January 8, 2019 Share Posted January 8, 2019 Its one of the bulkhead to engine loom/chassis connections adjacent to the clutch master cylinder/pedal assembly, Quote Link to comment Share on other sites More sharing options...
neil110 Posted January 8, 2019 Share Posted January 8, 2019 (edited) Later models have much lighter duty connectors. Best bet is to locate a connector with the same colour combination, or one very like it. Probably in cream coloured or translucent plastic rather than black rubber. Just as a by the by, a fully charged battery should be giving you 13.2 volts Edited January 8, 2019 by neil110 Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted January 9, 2019 Share Posted January 9, 2019 And a dead battery can still float up to the same voltage as a good one, only to collapse under load. Quote Link to comment Share on other sites More sharing options...
neil110 Posted January 9, 2019 Share Posted January 9, 2019 All Lead acid batteries (Gel, AGM, Flooded, Drycell, etc) are made up of a series of 2.2 volt cells that are bridged together in series to reach their final desired voltage. For instance, a 6 volt battery will have 3 cells (3 x2.2= 6.6 volts), a 12 volt battery will have 6 cells (6 x2.2=13.2 volts) and so on.That 2.2 volts is the fully charged, straight off the charger number. The actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery. These numbers assume 100% healthy cells, and may vary a bit lower for older batteries. A heavy discharge tester will soon show up a weak battery Quote Link to comment Share on other sites More sharing options...
