Tiger Late

[Altmeier karsten]

Hello,my Tiger 1 late has no Power in Grass or Mud when steering the fuse 40 Amp blows.What is the Problem.The Batteries where new 28 AH

Hi Karsten

This could look like you have some bad connections in your wiring. Look for loose cable conections and make sure everything is ok.

Remember, when you do 360 degree spins on grass, it really put a heavy load on the electronics. Guess you have enough power when driving in a straight line on grass and mud.

Are you using standard Armortek components?

[Altmeier karsten]

Thanks,sraight forward and backward is ok,cables ok all armortek standard.the dip switches all off.

[Armortek]

Hi Karsten, if you are using the latest Motion Control Module, then the fuse for the main drive motors is rated at 60A not 40A.

Hello the motion pack is three years old

[Christoffer Ahlfors]

No, bad connections don't blow fuses. They melt the contacts where the resistance is too high. This has to be a mechanical issue. When you built it, did you put it on stands and pulled the tracks by hand to check for bindings (with the motors still unattached)? If not, I suggest you go back to that stage. First, however, you could check that the road wheels turn without binding. That's easy to do, just having the model on stands. The prime suspects are the sprockets and idlers. A fault there *will* draw significant current. The sprocket can pinch the two bearings together, especially if you have washers on the shaft. It can also rub against the housing Allen screws. This will be very apparent if you turn the sprocket by hand without the motors attached. When clear, you can reattach the motors and see if the sprockets are turnable by hand. This will drive the gears backward and is heavy, but they should turn without too much effort nonetheless. A loose motor could get the gear out of alignment and jam it. The idlers also have two bearings that could be pinched if not attached properly. If they are not fully seated, for instance.

Good luck!

The tracks, motors,idler all ok no rubbing att hull side very easy rotation.i think the failure is the controller from the motors(4 dip switches) at the videos from armortek tigers they drive easy around and fast speed.

Hello Altmeiser, I do know that you need to have the 'Dip' switches correctly set. I recently experienced a problem with the drive system. One of the issues was one incorrectly set dip switch. Mick.

[Mark Heaps]

Fuses blow when excessive current flows through them. That is their job and what they are designed to do.
If the vehicle is performing okay in a straight line and the fuse blows when you try to turn, and nothing is binding then go from a 40 amp to a 60 amp as suggested. Armortek must have had a reason for changing from 40A to 60A. You may have a motion pack supplied with 40A and advice afterwards was to change them out for 60A.

Hello
The Promblems i wrote are already exists i dont know what it is.I mean the original motors have not enough power.The Dip Switches all Off Position.

Hi Karsten,

Can you post a couple of pictures of the motion control unit with the top off - especially of the dip switch settings.

thanks,

Hello Karsten

Having read your reports here, and seen the responses in which everyone has tried to help, I can add one
thing only. Your model is showing all the classic symptoms of flat batteries. I know they are new, but I strongly
suggest that this is the cause of the problem. Remember a fully charged pair of batteries should read
between 28 and 30 volts off load. If they are reading 24 volts off load, they are not charged and your tank will
behave as described. What type of battery charger are you using?

[Adrian Harris]

And if possible, check the voltage of each battery individually, rather than as a pair, to check they have roughly equal voltages, especially if they are charged at 24v.

If they are charged together at 24V but have different internal resistances, they will charge to different peak voltages.

Adrian.

I used e cetek charger 24 volt
