Make sure the your regulators and window runs are clean and lubed to avoid possible damage from your newfound power. If anyone knows if the later models use the same wiring setup, let us know!
Oh wow. That window was like a speeding race car after the install. I didn’t get too involved with the technical part of it. I’ll leave that to my mechanic. 👍
I have a similar problem with my 88 Cherokee. The electric door locks operate slowly in the front and not at all on the back two doors and hatch. Have a really bad voltage drop.
Hey, I just received a 89 xj wagoneer, and unfortunately, power windows motors are weak. Living in France, the booster you linked isn’t available. I ve found some electric booster 12-19 under 8A. Meaning 152w. No chance it’s gonna hurt the electric system? No risk of heating? Thank you for your reply !
You are applying more voltage to the system than it was designed for, so I suppose that there is some risk of a shortened life for electrical components. Alternators put out up to 14.5 volts, so the difference isn't quite as great as it seems. I think that if you could find a booster in the 15 volt range that it would be perfect. I'm willing to take the risk to have functioning windows. I think that an under voltage struggling motor is probably more detrimental to its longevity, but I am not an electrical engineer by any means.
Unfortunately that's not the case with many of these old Jeeps. The window circuitry and power lock circuits were barely adequate when new with excessive voltage drop and after 30+ years they just don't function well. I did clean all contacts and connections with Deoxit as well as add star washers under the grounds. I'm sure that the motors and switches also have more resistance than new and the regulators probably have more friction as well. The only thing that I haven't done that may help is replacing the window runs, which I will be doing after paint. If you have something that has worked for you, I'd like to hear it, but there are thread after thread on the forums of people looking for solutions for these things. Some have resorted to adding a bunch of relays. I liked this solution because it required almost no modifications to the wiring or vehicle and is easily reversible.
@@securedigital1most 12 volt automotive components are rated in amps. The converter that I used is 19 volts and 6 amps, you are correct that calculates to 114 watts. According the the electrical calculator even 6 amps @ 12volts equals 72 watts. You can find electrical calculators online if you'd like to look for yourself.
That is correct. Most 12v automotive items are rated in amps, but 19v @6 amps equals 114 watts. 13.8 V, (normal alternator output) at 6 amps would be 82.8 watts. There are electrical conversation converters online if you'd like to play around with them.

Looks like a nice improvement!
It is!
Good work Trey. Looks good.
Thanks Hunter!

🤣 thank you for watching 👍
👍
Definitely made a big difference
Thanks for watching

That's my next project. My locks are pretty much the same.

It's awesome that you have an XJ in France!
I would think if al the grounds and 12v connections are good, and the battery is strong, the window would work like new.

@@campoutwestus that transformer is 114W ! should a smaller one work? I think window motors are around 15W
