well if you have to ask maybe you should get someone more familiar with electric trucks to take a look at it.

But... on that note...
this forum strips url's from entries so you will have to remove the spaces i added from the url and copy and paste it in your browser address bar at the top to go to the site page.

a EV100 panel looks like this:
h t t p ://w w w.fsip.biz/Documents/EV100.pdf
the reactor usually has a decal on it saying EV100

a EV1 panel looks like this:
h t t p ://w w w.fsip.biz/Documents/EV1.pdf
the control card usually has a decal on it saying EV1

a 210 panel looks like this:
h t t p ://w w w.fsip.biz/Documents/M210.pdf
no identifying decals, you just have to know what this one looks like

if none of these are what you have then go to that site and look through the panels they show and find the one you have and let us know so we can help you.

good luck
