You may have saw previous post about battery well..
So I had a window cleaning company install my second pump and controller I thought sod it I'll pay and get it sorted done nice and neat but I'm left with an electrical problem
From what I have cuducted and I did go back but the electrical side of things they are limited to help and I'm annoyed as when I took the van in,my side was working and charging fine of the split relay but to break this down
New controller and pump installed quote a lot of new wiring coming from the 100ah leisure battery for the new pump and controller which is on the other side so quite a lot of doubled up wiring
The lesuire battery voltage seems to be okay at 12.3 or more but it's not putting much out for long the controllers say 11.5 11.3 and goes right the way down pretty fast but the battery seems to be 12.3
The old relay which worked fine for 6 years decided to not do anything when I got it back so they had me buy a new that new relay seems to be showing 14.20 now but when I turn the engine off the output to the controller and pumps doesn't last long a few mins before it shows very low voltage but the battery is at 12.3
Can anyone sudjest some help at the moment I wired the main battery and the window cleaning battery together im working of both but terrified incase it messes up van battery some jobs take time and I have no choice oh also with both pumps tuberd up even when both battery's are joined the voltage drops something has gone wrong with power since he added that second system as neat as it is
It's got me in a pickle
If you're anywhere 30miles of north surrey and a wizard at these sort of things you'd be a legend to help me out I've spent a lot already and really annoyed that something obviously really simple if you know what you're doing is causing such problems I only got that second system to take someone on once or twice a month now don't know if I can work normally myself
