Re: [MBZ] Cruise control soldering

I think that the pound of 60/40 multicore solder that i bought in 1968 will probably last though my son's and my grandson's life times . . . On Sat, May 20, 2017 at 8:12 AM, Jim Cathey via Mercedes < mercedes@okiebenz.com> wrote: > The solder I use is the old stuff, with lead. > > -- Jim >

Re: [MBZ] Cruise control soldering

The problem is the lead free solder, it was a fairly new thing then, and what they used cracks badly in use. Takes out relays, especially smart ones, CC amps, and PBCUs. Can be an issue with engine electronics too, not the "brain" so much as the connectors coming loose. Peter

So your theory is this guy is replacing the caps but in reality if he just hit the solder points it might have been good . Sent from my iPhone > On May 18, 2017, at 11:05 PM, Jim Cathey via Mercedes > wrote: > > I must disagree about the halfway job. I've done more

Re: [MBZ] Cruise control soldering

I must disagree about the halfway job. I've done more than a dozen of these, and every one worked when I was done with it. Several took more than one resoldering. VDO did a bad job in those years. And if you don't remove the conformal coating, you get a bunch of burned varnish all over the

Re: [MBZ] Cruise control soldering

I did find this post which seems to answer the questions. Next step would be to order, but first need to locate my soldering iron. http://www.peachparts.com/shopforum/tech-help/313824-how-cruise-control-amp-repair-14-pin.html On 5/18/2017 9:39 PM, Kaleb C. Striplin via Mercedes wrote: So

Typically, yes. In my case it starts out at 105 when it’s in the low 70s and by late i the day when it’s in the 90s it’s off the scale - it just goes blank after hitting 140F. Thermistor is another Mouser part, about $2.00. I bought three of them so I could have a couple spares. I think

Re: [MBZ] Cruise control soldering

Does a bad thermistor you are getting ready to replace cause he temp to read wrong? My 95 shows 51 when it's another 81 outside. Sent from my iPhone > On May 18, 2017, at 5:57 PM, Dan Penoff via Mercedes > wrote: > > I don’t buy into the “reflow every joint” approach

Re: [MBZ] Cruise control soldering

I don’t buy into the “reflow every joint” approach on cruise amps, as it’s been my experience this rarely yields results. What you need to do it find all of the electrolytic capacitors, which will be probably 8-10 total on the circuit board, and replace them. You don’t need to strip any

[MBZ] Cruise control soldering

I pulled the cruise amp from the SDL with the hopes I had a similar one laying around to try. Only couple I found are from 79 and 81, the pins are the same and might work, but maybe to exact or something. Anyway I pulled mine apart. What is it you are supposed to solder? The joints where the
