Battery Health & Charging Circuits

CDHE: The Cylinder head Temp gauge probe end is a ring that replaces a spark plug washer. I can't recall cylinder head temp averages but most air cooled 4 stroke motorcycle engines cylinder temp range is approx 300f(150c) to 400f(205c) - very useful instrument. Tried an oil pressure gauge but had too wide of a range as oil pressure in Breganzies are around 3 to 5 psi max and barely registered; however, the needle did move enough to indicate flow - Never did find an oil pressure gauge with say an 8 to 10 psi max sweep so I replaced it with an ammeter gauge to balance out my instrument cluster design (Do not include the starter circuit when using a manual ammeter gauge ;o)

Thanks. Will be taking a Ducati E900 on a trip through the Utah desert in about a month, and have been pondering how best to keep from frying the thing in the heat. Swapped the carbs out with a set of Mikuni TDMR's. Think its tuned well for my altitude (6700ft), but there will be a bunch of up and down. The original diaphragm carbs handled the changes well.

Ducati 900E , What's that late 90's - Sorry but the last Duke I saddled was a 72 750S Desmo and love it for handling " EXCEPT" you were down 1/2 the time adjusting the valves if you dared to rev it over 7000rpm.

My 70 Breganzie 750 SF0 would eat that Ducati up revving 7400+ approaching 8000 rpm all day long, year upon year and mile upon mile for over 45 years (Not saying I didn't have to rebuild the engine once or twice on my wife's kitchen table ;o)

I dream' t about Ducati 900S Desmo Darmah's, MV Augtusta 750S's and Guzzi 850 Lemans's but the last bike I had to sell was my 70 Breganzie 750 SF ;o(

Living in Northern Ontario Canada no Harley could beat my Breganzie on the top end nor beat her to an end stop after a day of touring the Cambrian Shield; other than, I can not recommend a 76 AMF Harley 850 Shovel Skirtster enough if you live in a city. Extremely well balanced, strong smooth torque with enough top end to conquer city streets. Very comfortable ride I have to admit - like any motorcycle of that era the AMF Harley 850 Skirtster does require specific maintenance - Lovely Motorcycle in my opinion ;o)

Good Luck Keeping that Relic alive and enjoy it - Italian rides are RACERS at Heart ;o)

Probably "number"BA fastener as many were in the day, electric and electronics. HTH j
Lucas gets decried as the Prince of Darkness, sometimes justifiably, but some Lucas gear is OK. The few Lucas switches I've looked inside had nice chunky contacts that would carry decent current, but the some of the cast metal switch housings are made of cheese. Good advice for Lucas switchgear is don't tighten the screws like a gorilla on steroids.

The last Lucas switch I repaired was the indicator switch out of an old (Series 1?) Landrover. The screw threads in the cast housing were OK but one screw was missing. I wanted to replace it with a new screw of the original thread, but I never did figure out what the fine thread was. I spent ages online trying to find something with the same diameter and pitch. Went through all the thread charts I could think of, including BA, and even American threads, but couldn't identify it. I dunno why any manufacturer would use such an oddball thread, unless it was something readily available in the day (1960's) that's since been discontinued. I think I fixed it by re-tapping the threads for screws that were actually available. The owner of the Landy wasn't fussed about originality.
 
The only oddball thread I struck regularly in Brit Stuff was 26TPI cycle thread. The only 2 places that carried those nuts and bolts were Alparts in Redfein and, oddly enough, Metric House on Victoria Rd Haberfeild I think?. BTW, I gave all my Imperial Spanners away so I would never be tempted again to acquire an old British bike.
