My thanks to this news group and several websites that decribe the
main relay problem. I had an intermittent problem with flashing
sports light and check engine light for 5 years. It was getting bad
enough that I was going to donate the car. Dealer wanted to
put in a new transmission. A mechanic said he replaced the main
rely. I finally took out the main relay myself and found bad solder
joints exactly as pictured on several web sites. Bought a new one
for $40 (too timid to try fixing solder myself). Problem is solved.

Thanks again.

Did he charge you for it?

Until the new relay gets the same problem.

I believe that people who have resoldered their original relay have had no
failures since,but a new relay may develop the same fractures.

(makes me wonder if the relay maker used the right solder alloy for the
job???)


Now if you still have the old relay,you could find a friend who knows how
to solder and has the tools to re-do the old relay and keep it as a spare.

i think that's just a matter of time. i doubt anyone that's re-soldered
has had that relay in operation for an additional 10+ years.

no, parts are subject to physical stress. a big no-no for solder
joints. bad design - depending on manufacturer objective!

indeed - need a higher wattage iron for that relay - some big copper
parts in there that will suck the heat out of a lesser iron and make
crappy joints.

i second that. personally, i prefer to replace, but soldering
/definitely/ revives a sick honda most admirably.

IIRC,some people here have had MR failures 6-7 yrs after purchase.

The MR on my 94 Integra GSR lasted longer than before it was re-soldered.
(and failed about at 7 yrs)

Too bad that car got stolen,stripped and torched last month. :-(

Now I have a 2003 Sentra SE-R Spec V.

I've been reading over on sci.electronics.design about the many different
solder alloys manufacturers use on wave-soldering lines;some will fracture
more easily than others,some may crystalize sooner.(and then fracture)
The new lead-free solders are even worse;lots of NEW consumer products with
fractured solder joints. Some solder alloys are not as ductile as others.
