Hi Thanks in advance for any suggestions, I have searched through past messages and havent found anything helpful to my caseturn the key and the dash lights come on slowly and dimly, turn to start, nothing, lights go out, will no longer start with a boostturn key to on, turn on headlights and dash lights fadeCar : 91 saab 900 2.1 litrebattery voltage is 12.75has been not starting lately ( bought it 3 months ago, always seemed to turn over slowly), every few days would need to take a boost and startI have a 100 amp booster/ battery charger that i used to boost previously and it worked, hasn't now though, although the dash lights get nice and brightStarted looking at cables and positive cable to starter solenoid was frayed and corroded a bit, about 2 inches before it joined starterreplaced cable with canadian tire 61 inch cable, has not started sinceHere's the kicker, when replacing the positive cable back to battery, wrench slipped and bounced off sidewall of engine compartment, sparked a bit. - probably fried something there and caused current(pardon the pun ) problempreviously to replacing cable, would start with a boost, all dash lights came on fine, just turned slowly when starting, there was no parasitic drain, I remove the neg cable clamp to battery and tested there was .3 amps when nothing was running, apparently acceptableI thought it may be the solenoid, replaced it, while I had the start out, did a bench test with old solenoid and it spun the starter, replaced solenoid any way, as it was out and I had already paid for it!read more stuff on the web ( Haynes book is on order, wont be in for another 2 weeks ) tested terminal 50 on solenoid, connected to terminal 50 spade connector, (not term. 50 itself) got 5 volts when key was turned to start, apparently thats too lowI have tested that I have good voltage at solenoid, also tested resistance of new cable, 0 at bracket that pos cable connects totested resistance of negative cable to bolt on engine, 0,...

It's a Fluke 29, but I think most any Fluke will have a 10A measuring range, it's actually good for 15A for several seconds. They're the best meters money can buy, nearly indestructible.

Thanks, I'll take a look. I'm using an ancient (20 years old?) Fluke, so maybe it's time to upgrade. Never had an excuse, since it keeps working.

They're about $200 new, but look on ebay, I know people who have picked them up for under $40. Fluke still supports their stuff, they do reasonably priced calibration and repair.

By your advice, he'd just drain the new one. Thanks for playing.
