Uh Oh! Main Fuse Box in Engine Bay is Melting (PICS)

I just picked up this 1990 DB1 GS and just noticed a problem in the Main Fuse Box in the engine bay. 3 connections have obviously got hot and are melting.
It’s not blowing fuses and everything works in the car except the antilock light is on in the the dash cluster.

Anyone else have this issue? Any ideas what’s up or is this something to expect from a 22 year old car?

my 91 DA9 GS looks about the same on those plugs… As long as all the fuses are correct (which looks like the case)

ABS light is non related issue could be a faulty ABS sensor or too much brake dust on the wheel hubs. Behind the rotors ABS models have a notched ring (gear pulser) on the hub with a small black thing (ABS Sensor) just above it… If the Sensor goes bad (small black thing) & stops getting a reading and can throw a code. ( this is all speculative as I haven’t had issues, but deduced this through observation and fundamental understanding of how ABS works)

good article for reference http://www.team-integra.net/forum/blogs/jacksont001/191-trouble-shooting-gen-2-90-91-abs-codes.html

Check the ECU for a code pull back passenger carpet and look at the kickplate. there is a small clear hole at the top with a blinking LED… it will be what gives you your code by a series of long and short blinks.

do you have issues where sometimes you brake and the car gently pulls left or right?

if i remember, mine look the same as well

[QUOTE=integra_hot;2278677]if i remember, mine look the same as well[/QUOTE]That brown stuff? That is some kind of waterproofing paste or grease, similar to dielectric grease, that Honda put on the wires back in the day when the car was made.

Other connectors have that also. Starts out clear or cream colored, then it turns brown after some time. It discolors whatever it has been applied to, wires, connectors, etc. If you are concerned, take the connector out, and clean it and the wires with rubbing alcohol or contact cleaner spray, re-coat with clear dielectric grease, and plug it back in, but I am leaving mine alone.

If that is what you are looking at, that just means the connection has not been touched or messed with in any way (which is good). (other hondas are the same, noticed this before)

Thanks guys,

I drove the vehicle with every light & accessory on and checked the connections with a infared thermometer and they weren’t hot. They didn’t even feel warm to the touch, so that’s a good sign. I won’t mess with them as the wiring is a little brittle and I’ll end up screwing them up with my luck. LOL!

No, no pulling issue when I brake.

Time to troubleshoot the alb light.

Your problem is a connection problem, when wiring looks burnt at a connection point, [and no fuses are blown] it is because of a poor connection, it may take some time to notice any heat build up, the “brown” wiring and the “boiled” dielectric grease tells me the connections have been hot.

Unplug the connections, spray the terminals with WD40 plug them in and out a few times to clean them before leaving them plugged in, check temp. after any long drive to confirm heat is no longer a problem.

What you do not want to do is ignore it, the white/red lead connection has gotten hot enough to start melting the plastic plug itself, if ignored it will leave you stranded at the most inopportune time, at night, on a dark road, when it is raining, when wearing your glad rags, with a hot date in the pass. seat and the very hard to get tickets for the concert you have waited a year to go and see in your pocket, get the picture. :bang: 94

[QUOTE=fcm;2278982]…“brown” wiring and the “boiled” dielectric grease tells me the connections have been hot…[/QUOTE]I have that same “brown” grease on my car. I have also seen it in places that have no reason to get hot, and I have a tube of old (like, a decade+) old grease that turned brown over time, compared to new dielectric grease.

Not saying you are wrong about cleaning and checking connections (that is a good idea on any old car), but this is just what happens to the grease Honda put on back in the day… it turns brown (shrug).

the car is fine, no need to go through all of that

2 of my employees have integras as well. One has a 93 DA and the other has a 90 DB. Both those vehicles have the same issue as mine.

Like I said, it is a connection problem, common with that type of connection, [not just on Integras].

Clean the contact terminals and it will be fine, if the terminals are loose, you can de-pin them from the plug and “crimp” them a little tighter, however if they got real hot the “spring” will have gone out of the terminal and they will just loosen up again as soon as you plug them in again.

If the terminals look like they have gotten real hot, [easy to tell once de-pinned] you may have to replace the terminal.

Also, if you take the advice integra_hot posted, you may well end up on that dark, rainy, side road.

Better to be safe then sorry. 94

FCM!! Please school me. what are “glad rags”?:stare:
