Title: How to check if my alternator is 450w or 700w?
Post by: zalle on February 16, 2017, 02:40:39 PM

My K1100LT was made in May 1992. Is it the 450w version? How do I check this?

Thanks

450w alternators have the fan on the outside, 700w alternators have the fan inside the case.

Unless it has already been upgraded yours will have the smaller alternator.

The feed into my 600sqft shop is 600V 100A 3phase. Hmm ... a tad of overkill.  :hehehe

greetings...

if my canadican to usa conversion is correct... that would be 1.0 volts and 0.1 amps and 0.005 phases per sqft...

impressive... (https://www.google.com/search?q=great+white+north&rlz=1C1TSNP_enUS724US724&espv=2&biw=1094&bih=487&tbm=isch&tbo=u&source=univ&sa=X&sqi=2&ved=0ahUKEwjVkYmyhpbSAhULzIMKHbxfCaEQsAQIRw)
