The batteries are charging in the scooter. Both batteries are the same make, type etc. The charger is 24v.

The battery is constantly being charged at 15.5v, this is not normal. It is being overcharged which is not good for the life of the battery and can be dangerous. Please note this is not a car battery nor a car's charging system. I'm trying to find the reason why it is being overcharged, as the...

No the original batteries were not holding a charge. The terminals are the correct way round, I mean the position of the battery when seated in the scooter. I have the original 24v chargers that came with the scooters when bought new. Basically one battery is charging at over 15v, this will...

I picked up a couple of second hand electric razor scooters with charging issues. The batteries would only charge for a few minutes then the fully charged light would come on the charger. I figured the batteries in the scooter ( 2 x 12v SLA) were needing replaced. I replaced the 2 batteries in...

There is a much smaller tank in the loft but the water looks quite stagnant, could it be blocked or something? I havent tried no will give it a go thanks

I don't know where the air was coming from the last time. The pump was noisy and I suspected it was on its last legs but I wasn't convinced it was the pump that was causing the air in the system. The engineer said the pump was needing to be replaced and he said he could hear the air in the...

does anyone have any ideas what the problem could be? thanks in advance

I switched the heating on this morning and it was running quiet, but that's normal, it runs quiet when its cold. Its only when it starts to get warm the whistling sound is there. Sure enough as it slowly starts to build temperature this morning, the whistling noise/air is creeping in. I...

I'll try adjusting the valve but there are no numbers on it? The pump is a Grundfos UPS2 15-50/60, it's set to speed number 2 (the middle one)

Yeah the middle pic is displaying correctly. The original pump was in the same position too.

We had air in our central heating system last year, it started as a whistling air sound in the boiler but eventually got so bad the pipes started banging and the heating was failing constantly. I had to bleed the pump and radiators to keep the heating on but we eventually had to get an engineer...

I think our cp53 is on the way out. We came home last night and the heating was off, when we switched it back on we heard some loud pulsing noises shooting up one of the pipes followed by the boiler switching off again. The noisey pipe has the cp53 pump attached to it. Some air escaped from the...
