Rasptank-super rookie question

1610899768

My son and I are building the rasptank.  Early stages.  We've put the raspberry pi and the motor hat together.  Followed all the steps: have charged 3.7v batteries inserted properly, plugged snuggly into the power port, switch on and there's no lights.  It is not showing up on the network scan either (just in case power was on but lights were down). Soooooo... how do I start troubleshooting?  My battery tester is only for reg batteries but the charger shows that they are fully charged.  
Any ideas?
Thank you,

Hi Mam,

I am also new here.  Just built a mars rover.
This one works probably about the same.
You can try the following:

The batteries should connect to the connector on the Motor HAT that says Vin (Volt in).  and the switch on the Motor HAT must be set to ON.

You can also try to set the switch on the Motor HAT to OFF and connect the power adapter from the raspberry directly to the raspberry.

If the raspberry still doesn’t boot up,  take the raspberry out..  connect it to a screen (and keyboard and mouse).  When you connect the power adapter it should boot up from the SD card.  If it doesn’t you can check the software on the SD card.

I  hope it helps to make a first step.
Greetings Raoul.

Thanks.  I'll give this a try.  The Raspberry does power up.  The motorhat does not. I'll check to see if I have the start up correct on the disc.
