RE: Alternator Installation

[Terry Rudd]

Michael,
I've attached the article I did for Zac in case you couldn't find it in the
archives.

There are a few disclaimers that go with it.
I used to wire external Bosch alternators into 1600's in the 70's (sometimes
2 of them using the a/c bracket mounts under the exhaust). I don't think we
butchered the original look too much to fit the Bosch reg (alloy cover with
yellow tape around it) but usually the original wires were spliced into an
original Bosch reg harness plug from a HQ (small right angled arrangement).

Hopefully the original 1600 wiring is intact and my article will make some
sense to you as a Bosch external reg alternator was never fitted standard to
a 1600 so you're working with a previous modification here which is always
fun.

regards
Terry

Yep Terry, the alternator should be easy as pie to wire up! Thanks for the wiring info, I should be able to wire it up easily now. I am thinking of keeping the old loom in there and getting it running, then swapping the looms later. I jsut want to drive it again!!!   zac   ----- Original Message ----- From: Terry To: [EMAIL PROTECTED] Sent: Saturday, November 04, 2000 10:00 PM Subject: RE: Bosch IR Alternator and Electric Fuel Pump Wiring!! Zac, 2mm is rated at ~8 amp continuous 4mm is 15 amp 6mm is around 25 amp 8mm is ~35 - 40 amp 10mm is 60-70 ish   I just can't lay my hands on the exact numbers for some of the ratings but I'm close enough   Does the wiring instructions make sense from the earlier post, i.e. does your car have those colours at the old alternator and the regulator plug.   Terry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Zac Campbell Sent: Saturday, 4 November 2000 8:12 PM To: [EMAIL PROTECTED] Subject: Re: Bosch IR Alternator and Electric Fuel Pump Wiring!! Thanks Terry, I picked up my slick new alternator today. A bluebird Bosch IR one. It's nice, pretty clean looks to be in top nick. $40. Also when you refer to 2mm and 4mm wire for the fuel pump, what amperages are these? 10 and 20?   Thanks again!! zac ----- Original Message ----- From: Terry To: [EMAIL PROTECTED] Sent: Saturday, November 04, 2000 3:33 PM Subject: RE: Bosch IR Alternator and Electric Fuel Pump Wiring!! Zac (& someone others wanted this, Michael & Paddy),   Disconnect both battery terminals   Alternator wiring (Bosch IR)   White/Red (thick wire)  > B+ (I recommend if you have over 300w headlights & a mega amp etc that you run an extra 6 mm shielded wire from B+ to the Starter Solenoid as the stock 510 loom wire is rated at 35 amps and turns into a cigarette lighter with the high draw and charge that your Bosch alternator is capable of.   Yellow > Ind Black (-) > (E)arth (some Bosch don't have a terminal so just use the screw on the back that's for a suppressor. White/Black (Field) > not used   Suppressor   Connect the barrel to the Alternator body and the wire end to the B+ terminal. A suppressor is not required at the old external regulator end so discard if one is fitted.   External Regulator (Hitachi or Lucas)   Pull the connector plug at the regulator Make up a jumper with 2 male spades and bridge Yellow to White/Red in the plug on the loom side.   Connect battery and start your engine. Check that the alternator is charging with a multi-tester and load test it with the lights on.   Fuel Pump.   Wire the relay thus: Pin 30 - fused power from battery (4 mm) Pin 85 - Earth (2 mm) Pin 86 - Ignition (2 mm) Pin 87 - Pump (+) (4 mm shielded) Pump (-ve) to Earth (2 mm)   * By shielded I mean run it inside that black stuff that's used on modern day cars that protects wires from insulation damage.   regards Terry       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Zac Campbell Sent: Saturday, 4 November 2000 2:33 PM To: [EMAIL PROTECTED] Subject: Wiring!! I'm still working on this loom but I am having some trouble working out which wires I can remove to let me install a Blueturd internally regulated alternator. I also need to know how to wire an electric fuel pump because mine isn't wired properly. I imagine it would be similar to the thermo fan wiring?   Thanks! zac --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
