  1. I don't get on here as often as I should, but I think I've been a member since around 2006 and now I'm a "newbie" w/ some sort of "icon" attached. (Where's the "index" for what "icons"-if that's the right word for them- mean?) Do I have to earn points now? Did I miss an "update" to the site or being punished for not getting on here often enuf or not being "tech-savvy? 

  2. After getting "locked out" (my non-computer term") since May or June 2020, I'm back and finally able to log on. God, how I hate "computer nonsense"!!!  Now I got some catching up to do. Dave

  3. I forgot to comment ....Paul Bell's modified wiring system (the diagram with the battery in the trunk) is very good!!!....maybe lacking a "max fuze" on the charge cable (I'll bet if he's a pro-audio guy, it is there, but just left off the diagram) 

  4. I have 70 & 72 (not a 71) service manuals....the engine bay charging system wiring is slitely different between the two. Wire splice location(s) & component locations vary, but operate pretty much the same. I will say that the "common component" is the "hot-at-all-times" buss-bar (aka: junction block) at the Horn relay. Battery, charge circuits and  "high amp accessories" end up "connecting" to that point, if not directly, thru a splice. Also, running two smaller gauge wires from point "A" to point "B" is not recommended in the "electrical community"....

  5. Consider this.....Without debating wire colours, but assuming the pink/wite is, in fact, "Ignition on, switched power" to the window switches...remove the O.E. relay and install a 30 Amp circuit breaker (C.B.). Supply power to the C.B.  from a "Hot at all times/battery power source". Consider protecting it with a 40 Amp fuse.  Doing this eliminates the need to have the ignition key in your possession AND in the ignition AND in the "ACC" or "On" position. Notes: 1) the PW circuit wires (except the "ignition on" wire) should be 10 Ga. Any thing smaller is asking for problems. Maybe not next week but in several years as they age.  2) check ALL wires that pass thru the door...they will likely break there at some point. 3) old, original 4-pin (drivers door) switch will likely become "touchy" during operation of the driver's window. It is used more than all the other windows, and will likely fail due to electronic arcing, as power is send to the 50 year old PW motor (Like the #@$% 3rd speed of the heater fan on a 50 year old AC car!!!!)  4) if you don't have one, get a FACTORY G.M./Chevy service manual, a probe light that indicates power and a "good quality" Digital Volt Meter {DVM} {If you get the $6.00 red colour units from Harbour Freight, get two.....so you can check that the 1st one is working. And, a couple of test wires w/ alligator clips.   Also suggest you photo copy the factory wire diagrams (to 11 x 17 size), that way you can mark on them (PENCIL) with changes, fixes, and modifications. I'm up to 30 or so "wiring drawings" on my Monte.   Don't panic, piece o' cake!  good luck.

  6. I've tried to reply to what may have been a private E-mail about this subject, but with all things computer...the simple things, that I have done before will not work as "something" has been changed. I did get an E-mail from "somewhere" about it not going thru, but it was written in "un-understandable computer gibberish". (I have a flip-phone)  I am now retired and no longer have the ability to print or scan. If any one wants a copy of my custom wiring diagram of this relay/heater control system, send a standard business-size SASE to: Dave Winters, 112 35th street SW, Loveland, Colo. 80537

  7. I've had this on most of my GM's w/ AC that have 4-speeds for the fan. Hard to nail down the specific issue which is the Fan or the switch itself. As the fan ages, it can be harder to get it turning, requiring more amps which can stress the wiring and the fan switch internal contacts. I've normally had the switch fail in the 3rd highest speed, (the one I seem to want to use the most!), while the lower two speeds continue to work. Also look for high heat build up at the "Max speed" in-line fuse and wiring that are in the engine bay...I've seen that get so hot that the factory in-line fuse holder "melts" slitely and makes max speed function intermittently. In 2007 during my MC Convertible build, I installed new fan, new switch AND 4 relays with it's own 10 ga. wire and Circuit Braker, so the fan load is no longer on the switch contacts. No law says you have to use that plastic connectour body...crimp and solder on a good female terminal and cover with heat shrink.   Example: New aftermarket electronic cooling fans normally require a 30 or 40 Amp Circuit Braker....this is for the high amps normally required to get the turning....Amp requirements drop while the fan(s) are running....it is that first start-up that is "arcing" at the GM fan switch and slowly destroying the contacts and causing heat build-up.  I'm installing a complete Vintage Air AC system as I write this, so I pulling the old system from 2007 and was "redlining" my custom wiring diagrams, so I was checking the site and saw your posting. The fotos I attached are of the "Relay System" I installed in 2007.

  8. Remember airplanes hunting "speeders" in the middle of Nebraska!  55 in the middle of Nebraska!!!!!  I remember Ohio as being one of the most oppressive.  Huge Fuzzbusters on top of the dashboard. What may have started as an alleged way to save gas turn into nothing more than a money-making scam. Government run-a-mock! Howard Cosell & Dandy Don on Monday Night Football! (Now its Troy Aikman droning on and on and on and on...……   The insurance companies loved the 55!  "...Well Mr. Winters we have just been informed that you have gotten yet another ticket for going 56, downhill, in a 55 zone......we better raise your rates….for your own good, of course, have a nice day!"   Convoys!  Putting in a "taillite switch" to alter taillite "signature", used if the "Gumball Machines" flipped a "U-ie" and came in pursuit.  Going over to Canada to "drive fast" on the 401 & QEW.    The "Cannonball Baker Sea to Shining Sea Memorial Trophy Dash" that Car & Driver put on. (I miss Brock Yates!). Sir, you have the option to"Pay the "always excessive" fine on the spot and get a reduction in points lost".  I may also remember an article in Car & Driver exposing an insurance company (It might have been "G****) for "donating" radar guns to various local governments....for the safety of the public!. Picking out "Smokie Bears" by their front parking lamps (Some Full Size Slo-Pars had park lites like the 69 Chevelle, only a litter bigger!).  "No 55 stickers".

  9. I'm looking to replace my Small-block $25 swap-meet aftermarket headers on my 72 Monte Ragtop.  I will also be re-doing the rest of the exhaust system which I'm not happy with....hangs too low, too close to the starter and is too loud at cruising (50-80MPH) speed. The current headers are not "Shortys" or "Long ones"....something in between. Not a drag car...engine is a 350, AT w/ Edelbrock 600 & Intake. When the car was finished over a decade ago, funding was a concern and I went "Low ball" on price and to a degree, installation quality. I've located the best "Exhaust System Artist" in the area, and am getting ready to pull the trigger.   So.....whattaya recommend for headers, and why?  Thanx, Dave
