battery hold downs for 521

04 February 2018 - 01:32 PM

My square box type batter hold down has rotted out and can seem to find any new ones near by. What are people using to hold down battery besides Rbber cord/Bungy staps.


I would like to use the stock holes on end with the threaded hooks.


They type I see now is the one that goes across the middle but the inner fender well don't have a hole or mount to use the hooks


Photos would help.


My option is to go across the top from Pos to neg side with a bar type set up and hold it that way but don't want to use metal in case it slides and hits the posts

Power Select(Alternators)

21 November 2017 - 02:17 PM

Rockauto has is starting to list Brand New made alternators for some of our Datsuns. Example 70 510s and 521s. I seen listed ofr 72 trucks also.


Has anybody tried these out?

Yes they are made in China. But my batch of Autozone ,O Rileys rebuilt in Mexico  cased Hitachi's  just isnt cutting it anymore. Nowe I see rebuit in China on the boxes(autozone, O riley) but these are NOT old Jap cases. So who knows


I dont want to run a huge alt in my 521



Anybody use the POWER SELECT? reviews?

521 no charge

My 521 is not charging again.Happen last night so no time to look at it.

The 1st fuse on the left keeps popping. THis time replace fuse turn key ON but no ignition light.

Alt is only 3/4 months old.


Fuck I cant get more than 6 months before this thing breaks again.

Last fix was a new alter. prvios fix was reseat the instrument panel.


aJust wonder if its the alternator again.

blowing Ignition fuse 521

24 February 2017 - 10:39 AM

Really its the 1st fuse Left on the fuse block. So maybe flasher ,reverse, instrument cluster


Driving to work my alternator starting squeling and I tighten the belt and notice on my diode type volt meter I wasn't charging.


So I went home found a fuse was blown  started up and then notice Im now over charging even with the High beams ON.

I swapped the volt reg out  cked out fineand it worked fine untell I heard the alternator squel again then bam im back to not charging.  I replaced fuse and now its over charging again. It s a solid state volt reg.

Fuse is blown again.


truck runs off battery so It inst the ignition fuse as sated in Title.


what you guys think. Datzenmike, Wayno ,Daniel??????


I have a spare alternator. to swap in and and spare Volt reg mechanical and solid state.


But really assume the alternator is good.


Im going to pullthe instrument cluster and clean it and maybe the fuse box.


If it wasn't for the volt meter im running I would have never known I had this proplem as my ignition light never came on and would have ran my battery down. So people run a volt meter or better yet those plug in Cig type with diodes and believe what it says.


MY bad luck I didnt bolt down the fuse cover with the labols saw it on road then a truck ran over it and don't have the labels


its the far left fuse that's poping on fuse panel

As on DPs thread it could be the rverse lights
