Toyota 7BRU18:
reverse polarity battery

I bought a battery and they sent the battery with the polarity reversed. It got hooked up and no the horn goes off non stop with power hooked up but i get no reponse from any other light or screen on the forklift. Is their reverse polarity reset or did my forklift just get ruined. Id love any help please and thankyou.

Go after battery manufacturer for all costs associated
Could have caused explosion or fire in your facility
And you should have reached out, alot of good cards in older trade ins that are getting scraped

So yeah just an update. After hooking it up correctly nothing happened. I caved and had a toyota tech come look at it. It fried the 2 main cards and the display card. It turns out they do not have any protection on this model. I have a company repairing the boards now. it actually blew 3 mosfets out on the one board. The other 2 were in cased but you could smell them. They had let out the magic smoke. Thanks for your help. For anyone reading this i can only stress if you buy a battery. double check the battery cables are hooked up to the correct terminals, not just looking at the color.

Standardised crash test dummies appeared in the 1960s. Over time, crash test dummies better replicate the size and anatomy of a human and all its parts, as well as the range of motion of limbs and joints. Today's versions contain sensors to record damage and respond as humans do.
