The joints you've soldered look ok. Really, you don't even need to use new solder. Just touch your iron to each joint to melt the current solder and then let it cool back down. All you're redoing is the one big connector. Some buses with more gauges have two connectors.

What's happening is the the weight of the connector vibrating eventually develops hairline cracks. Most of the time you can't visually see that the connection is bad.

And if you need a new soldering iron just order one from Parts Express in Dayton OH. Good prices and fast shipping.

I full relamped mine with new lamp socket seats and bulbs.. those socket seats are known to go brittle on international.. i had a couple bad bulbs so figured id relamp the whole thing so i wouldnt have to take it out again...

but yeah the last post is right.. the vibrations and weight crack the solder joints.. and if that connector has ever been unplugged and replugged it makes things worse..

I didnt use any new solder on my DEV... i tinned the iron then just barely touched each joint.. till it flowed then let it cool and looked at them all with a magnifier..

I did have to fix a separate issue on one of the resistors on that board.. it eas making the fuel gauge read E when i had 1/2 tank... resoldered that resistor and its been fine..

Ok so I got int othe dash cluster on my new Bus, and it came apart like what was described here (and in the service book).. the gauges just unplugged fro mthe main board.. no removing the faces like i had to on DEV..

I can assume oin DEV a previous repair was botched resulting in soldering the gauges to the board.. or perhaps since that was the first year (1990 chassis) of that cluster it may have been done that way before they made the plug-ins..

my new cluster has some real issues.. I found a small crack in one of the boards itself... it appeared someone may have tried to take the thing out of the bus at one time or maybe they flexed it to try and get it to work... not sure...

I soldered a couple jumpers across the broken board traces.. and then found some really bad solder joints on the connectors.. like their flow solder machine at manufacture was deficient... fixed those up.. and relamped it .. I had 3 burned out bulbs.. (these clusters use a '37' bulb).. so I changed all of the bulbs..

today will be the real test when I put it back in the bus and try it.. but it was in bad enough shape i may have to send it off for repair / replacement if it doesnt work..

Anyone know what size LEDs I should buy? They come in 3, 4, and 5mm.

these were the ones i was looking at..

T5 37 73 74 T5 LED Bulbs For Instrument Panel, Gauge Cluster Lights

our bulbs are a '37' size in the cluster like shown in the pics... that fits All of the bulbs in the cluster... background lamps as well as the idiot lights as well.. my only concern with LED's is will the light be spread properly...

the gauges 'sort of' have optics for the backlights but looks like a decent light spread is needed by the bulb rather than a spot like some LED's produce..

I havent bought any yet.. I wanted to repair my panel first to make sure i could resurrect the poor thing from its abuse before I bought any LED's for it..

if I can create a solution for the trans temp, air pressure, and amps im going to go Glass in that bus with a fully computerized panel...

Fully computerized sounds enticing. I was going to go that route but didn't find any plug and play options even for the speedometer and tachometer. Do you know where you're getting the replacements?

the 5 main gauges on the 'E' busses (DT-466E, T-444E,DT-530E) are data-link from the ECM (speed, RPM. oil P, temp, Volts)..

the gauges below do not go through the computer
trans temp - sensor to gauge (thermistor)
Air pressure - mechanical gauge (air line direct)
Amp meter - shunt to gauge
Fuel gauge - sensor to gauge

Silverleaf electronics makes a full glass dash solutiuon with external transducers and propreitaery software.. it is actually OEM in some high end coaches... and it comes with a high end price ($6k I think)..

they also make a device (vmspc) that will read the J1708 stream and you can make your own gauges and runs on a windows PC.. it is $400 I think.. in addition to the 5 main gauges it would allow me to read some of the problem children of the HEUI system like the ICP command and the HPOP..

what remains to be seen is if I can get hold of a separate device and feed into their box..

a windows solutiuon is best for me because i could window the screen with NAVI / traffic / Music , etc.. my plan is to use a Surface pro 4 with a ssecond screen attached.. allowing me the fkexibility of other apps ..
the silverleaf pricey solution does include the capability for cameras and what not just not native windows apps...

at the very least I could custom build a panel to fit in the factory spot , using the J1708 data for my main gauges and any other data-based info i want, and then keep my original gauges for the 3 that arent part of the data stream...
