On Tuesday my controller wouldn't power the pump tested batteries with controller it had a reading of 9.5 v .
Ordered new battery ,fitted this morning controller again wouldn't power pump checked wiring turns out fuse holder was faulty .
Tried pump with a old fuse. Holder attached controller wouldn't power up .
Managed to work with pump straight to battery relying on pressure swith.
How can you tell if controller is fried?

I think you need some punctuation in there bud as that's a difficult read but are you sure it's not just a bad connection somewhere such as on the fuse holder or the fuse itself? I would have thought if the controller was fried it wouldn't give any sort of display but I may be wrong.
Spruce or Ian will be along soon to help I'm sure.

As Simon Comments it would seem the controller has suffered a short of some kind. However it would be worth checking through the wiring and ensuring that any corroded connectors are replaced and replace any damaged cable where the copper core is exposed.
Two points jump out. First the battery volts. 9.5v is very low and the battery capacity is likely down to 20%. At that level the lead cells will degrade quite quickly. When capacity is so low the battery struggles to provide current to the pump.
When a battery has very low capacity rather than a steady flow of current, the battery generates current in sharp pulses. Some of the signs of this can be the pump giving erratic flow and/or sounding very quiet. These current pulse can cause a current spike.
Second a badly worn or corroded fuse/fuse holder is not likely to give good protection in the event of a current spike. In good condition a fuse will open ( blow) in around a 1000th of a second. But a badly corroded fuse may just slowly warm up and not open at all.
Depending on the age of the controller it can be checked out to see what has happened, However if the controller is more than 3 to 5 years old it may be better to replace it.
Due to family circumstances I will not be available from later this evening until Monday 29th, So dont worry If i appear a little slow to respond.

The controller is less than 12 months .
The fuse and holder where not corroded it has a faulty connector .
Ian how can I get it checked ?

You don't say what the make of the controller is.
Spring usually ask for the controller to be sent back to Spring who manufacture them provided it is their controller to begin with.
If its a Varistream then the manufacturers are Williamson Pumps.
If its another controller then you need to get back to the place you bought it from and ask their advise,
Most of the windies who have had controller problems have been due to water contamination damaging the electronic components on the PC board or controllers that have been incorrectly wired up - reversed polarity.

It's a Spring controller . Definitely not been wired incorrectly.

Then you should post it back to Spring Europe for Ian's attention.
Recently he asked someone to take a photo of the PC board and I think they identified the failure was due to water ingress.
They have some way of knowing if the terminals have been monentarily connected up incorrectly and has blown the circuitary. My leisure battery is a permanent fixture in the van. If it wasn't I would have gone through a fair number of controllers by now.

sounds stupid by if my battery terminals arnt tight it reads like this, maybe a wire is corroded somewhere and just touching ?
-
Sorted it was the faulty inline fuse holder .20p repair cost £305 2 new banner bull batteries

Told you. ;D

Thanks for the advice you have both given Spruce and Simon.
Glad It is all sorted. :)
