[R129 SL] battery

[william hughes]

my 1995 sl500 looses battery charge even with brand new battery.
test shows a spike to 20 milliamps when the radio light blinks - ok
and a random spike to around 150 milliamps evry 30 seconds or so
almost to quick to see on the guage but shows on the recording
any idea what might be drawing
thanks,
bill
