OK this might be a daft question my diod has packed in on my soler it a 30 mile round trip to get on.
I have a box with sum bridge rectifiers in it
Would one of those work that only have diodes in them any way don't thay I might be wrong but I am sure someone will be along soon to sortmeout
19v open cercut DC in DC out would it work

I know nothing about solar panels, Bill, but I think one leg should work in theory

But a diode will only cost a few pence, why not wait until you can get to a store such as Maplins?

I Ned to get it working today as I am working the rest of the week 12hr shifts

Bugger. As I say, the bridge rectifier would appear to be usable in theory. Just that I'd hate to give advice and see things go wrong. Best to see if an expert on solar panels can advise

It's only 12v not like I am going to blow my shelf up but I think it could code a power reduction.

Use just the output side of the bridge rectifier. Connect - to source and + to load. Tape the input connections. You will have 2 diodes in series but it will work.

thanks so + to battery I will just put insulated spade on input connectors

Yes. The volt drop will be higher than for a single diode but it will be better than nothing.

Yay! As stated by Flamenco above, the volt drop over two diodes (0.6V/diode from memory) will be greater, so that will impair charging

Good news

A capacitor can either fail open circuit or short circuit. Usually they are across the supply in a M/H, so a short circuit will almost certainly blow a fuse in that case. A open circuit cap wouldn't prevent power from getting through, but could allow power fluctuations to get though.

Caps can sometimes be used in series with the supply, to allow audio or radio signals to get through and prevent DC from doing so. I'm unsure where that would be used in a M/H, perhaps and aerial, audio or signalling circuit. In which case a short circuit will cause interference with that signal, an open circuit will stop everything from passing through.

Sorry it is so generalised, need more information to give you a better answer

OK my wielder stopped working it was the capasetator could no get exact mach but got one with same values.
Only thing is I threw the old one in the bin at maplines and I an not sure now what side is in + and what side is out can anyone help.

Ho de ho, Ian

On the cap, looks like it is non polarised, Bill. Means it can go in either way around.

Great news. I would still change that bridge rectifier for a single diode when you get the chance, though. Make sure the current rating is sufficient to do the job

Oh, bugger, you are going through it mate. Hope the little fella is all right
Its my eldest grandson was bmx and got it wrong about 1800 hrs to night.
Waiting on an other x ray of his knee as he is complaining of other bits now :confused:
