Aixam mega city service spanner reset

Hi everybody,

I`m new here and in electric car business as well. I bought a faulty Aixam mega city with charging fault few month ago. I managed to fix the charging fault which was quite easy (thanks for google search). I just had to replace 2 cooler fans in the onboard charger. But it wasn`t the only fault with the car as you can expect from ebay purchase. :/ 2nd problem was a 12V power problem. Dash remained dark all the time. I found a faulty relay which is actually energizing the DC/DC converter for 12V power line.  Finally I could see everything on the dash. Unfortunately the battery bank was sitting uncharged for a while at the seller of the car. I could charge them up but as I expected I couldn`t drive the car too far. Let`s say I could reach the bottom of our street and back. So the battery last in 400 meters. I purchased “Battery Extra” recondition device (I thought it worth to try) but it seems it doesn`t work unfortunately. After the 3rd charging period the condition of batteries just getting worse. They already last within 50 meters. Accidentally I found one more battery under the dashboard! :) I didn`t know there is an “emergency” battery fitted in possible for safety reason. 3rd problem this battery had a short cell and it was swollen and hot. Hope came back, but this time I already discovered the service spanner coming up on the dash. Also when I`m switching the gear stick to N or R it doesn`t show on the dash. It`s just showing D all the time. My thought is this shympton is linked to service spanner on the dash. Maybe I`m wrong maybe it`s all just because the faulty battery bank but I can`t find any useful service document for this little car and I don`t want to spend 1000 quid for a new battery bank if it won`t work after.Sorry it was a bit long.

Does anybody know how to reset the service spanner in the Aixam Mega City? (Normal aixam method won't work)

With a low pack voltage, you are not going to get far or get the vehicle working properly, if its a really low voltage, then thats likely to be the cause of the spanner. You need a replacement set of cells. I recently supplied a set for a Mega Van, dont be tempted by cheap leisure batteries, they are not up to the current loads. Where are you located?

Hi Grumpy-b,

Thanks for your answer. I'm in Ashford, Kent. How much was the cost of battery pack for you? I'm not sure that I really want to hear that!

To keep his costs down, and he didnt need the range , he went for 8 rather than 12 batteries and the 8 cost him about £1200, but I would expect them to cost more now ( a few months ago) as stocks of the decent Yuasa batteries are not particularly high in the UK, so price tends to follow currency changes quite quickly. The price doesnt include carriage , as I also fitted them.(not within the price I hasten to add)
