Electrical problem
1993 Lexus ES 300 6 cyl Front Wheel Drive 155000 miles

Okay so my 1993 Lexus which I bought about six months ago stopped keeping a charge in the battery. Figured it was a dead battery, it sat in the driveway for about 6 - 8 weeks as I had no need to drive it. Took the battery into the store, bought a new one. Put it into the car only to find out as I was trying to attach the negative terminal that the battery was reversed in sides from the original. To make sure the car would start I took out the battery and hooked it upvia jumper cables to my car. Turned the key and nothing happened no light no sounds. Thinking that maybe the issue was that I misinterpreted something, I reversed the cables and then still have nothing. After taking the jumpers off I found that the battery produced no spark at touching the cables together, none. So now I don't know is it the battery, is it the electrical system, what? I am so baffled, never had this problem before, even with a 1992 Metro that sat in my mom's driveway for over a year started right up after a new battery was put into it. Any ideas?

Hi usfcire,

Thank you for the donation.

Hope you have not damaged anything seriously with the reverse connection of the battery terminals.

Check the ALT ( 120 A) main fuse in underhood main fuse box. It should be blown and you would have to flip the side open to remove the holding bolts on either side before the fuse can be pulled out for replacement.

I have checked all fuses I can get to and I have found that the ALT H-Fuse 100 A was blown, and that the 20A radio fuse was blown. Took the battery back to the parts store and they covered cost of the fuses since they were the ones that gave me the wrong battery, Kudos to O'Reilly. Also, that 100A fuse was a pain to get out, but thankfully it is out. I will write back after I have installed the fuses and new battery (with the proper polarity) and let you know how it went. Thanks for the tip!

You are welcome and glad that we are on the right track.

Always install and secure the positive terminals first.

Have a nice day.

Install the new fuse and new battery, car started up like new. All the electrical stuff on the inside works fine, so it does not look like any damage was done to the systems, just to the ALT H-Fuse and the fuse for the radio.

Thanks again!
