Damien Thank you for your kind words. We have grown a lot recently and we now have a staff of 7 at our Somerset location with 2 others (on the design side) at remote locations. We are all very friendly and helpful - try us out! With regard to the CP25. Currently, we have very little...

People Can you all please tell us what the original symptoms were that you were having? We have just repaired a CP25-K1 which is a Knaus special but I would think that the CP25-UK is probably similar. Paul

Rodone - We are very interested in your comments! Many people know us as offering repairs to caravan/motorhome electronics but our real passion is electronics design and the toilet flush is one of the things on our list! Currently our plan is to offer a replacement with a target list of...

The croc clips/12S idea is fine but there is nothing to stop you completely flattening the car battery. If you use the car battery through the normal van system then many systems have a cut off at a certain voltage to prevent you completely flattening the battery. Whether this voltage is high...

This does, of course, beg the obvious question of the usefulness/integrity of the test board the fitter was using!

Hello People I think there is some confusion going on here! Below are a few pointers! There are generally two 12V feeds from a vehicle electrics. One is a permanent live from the battery and the second is generally refered to as D+ and is only active when the engine is running...

Give us a clue to the make/model of your caravan/MH/charger/Fuseboard/control panel etc and we will try to help you!

Cypher Presumably we are talking about a certain Mr G? There are a few things that I think the forum needs to be aware of with regard to this particular issue as you are not quite telling the whole story! As you are no doubt aware, the particular relays in question have had the tops cut off...

Measuring across a fuse to determine voltage is not a reliable thing to do. You would measure across a fuse with an ammeter to measure current not voltage. If the load side that the fuse feeds is off then you would not measure a voltage. You should measure these pins relative to 0V/battery...

Which fuse! Are you removing the fuse and then measuring across where it would be? What make/model of board do you have?

Where exactly are you measuring on the fuse board/what make model do you have? Regards Paul Wright BSc MEng PGDip CEng MIET Chartered Electronics Engineer

Glad to be of service!

Glenno We can usually offer repairs and upgrades to most chargers/electronics/control panels etc that are a fraction of new - shame you did not contact us. If you still have the old charger then we would appreciate it for research purposes so that we can offer future repairs/replacements that...

Hi Peter Please can you give the make & model of the control panel and fuse board you have? This will help us diagnose the issue.

Welcome to the forum again and good luck with the business. Perhaps we can also help you out with the repairs to your electronics units! All the best Paul
